I still remember the first time I held a true Aogami Super knife. A friend who runs a sushi bar in Los Angeles handed me his personal gyuto, and the way it glided through a single sheet of paper told me everything I needed to know about why chefs obsess over this steel. That single cut sent me down a path of testing dozens of blue paper steel knives, and in 2026 the field has never been more interesting.
If you are shopping for the best Aogami Super steel knives, you are chasing the sharpest, longest-lasting edge in the Japanese cutlery world. Aogami Super, also called Blue Super or AS steel, is the top tier of Hitachi’s blue paper family, hardened with vanadium, tungsten, chromium, and molybdenum for an edge that holds its bite for months. Our team spent three months cutting with, sharpening, and abusing seven Yoshihiro knives built on the blue paper platform to see which ones earn a permanent spot in a serious kitchen.
One important note before we start. Only one knife in this roundup is built on true Aogami Super core steel. The other six use Blue Steel #2, the sibling grade in the same blue paper family. We include them because most buyers searching for Aogami Super also cross-shop Blue #2, and the comparison is genuinely useful for understanding what the extra money for Super actually buys you. We are completely upfront about which steel each knife uses in every review below.

1. Yoshihiro Super Blue Steel Hammered Gyuto – True Aogami Super Core
Yoshihiro Super Blue Steel Stainless Clad Hammered Gyuto Chefs Knife Howlite White Handle (8.25″(210mm) & Saya)
Aogami Super core
8.25 inch gyuto
Hammered stainless clad
HRC 62-63
Howlite octagonal handle
Made in Japan
Pros
- True Aogami Super core steel
- Razor sharp out of the box
- Excellent edge retention
- Beautiful hammered finish
- Lightweight and ergonomic
Cons
- Requires regular oiling
- Can rust if not dried properly
- Not dishwasher safe
This is the only knife in our roundup running a true Aogami Super core, and you can feel the difference the moment it touches a tomato skin. The hammered tsuchime finish on the stainless cladding looks gorgeous, but more practically it creates tiny air pockets that stop food from sticking to the blade. I prepped an entire box of potatoes for a family dinner without a single slice suctioning to the side of the knife.
The Howlite White octagonal handle is unlike anything else on this list. It has a cool, almost stone-like feel in the hand and the octagonal shape locks in your grip whether you hold it in a pinch grip or a full handle grip. Coming in at 8.25 inches, this is the classic 210mm gyuto length that handles 90 percent of kitchen tasks without feeling too long or too short.
What makes this our editor’s choice for the best Aogami Super steel knives is genuinely the steel itself. Aogami Super contains roughly 1.4 percent carbon with additions of tungsten, vanadium, chromium, and molybdenum. Those alloying elements are what separate Super from the Blue #2 knives further down the list, and the practical result is an edge that stays surgical longer between sharpening sessions.
The trade-off is the same one every Aogami Super owner faces. The exposed edge is carbon steel and it will rust if you leave it wet. The stainless cladding protects the body of the blade, but that thin cutting edge still needs to be wiped and dried immediately after use. Treat this knife right and it will outlast almost anything else in your drawer.
Who should buy this knife
This is the knife for the cook who specifically wants Aogami Super steel and is willing to commit to the maintenance that comes with it. If you have read the forum threads on r/chefknives and ChefKnivesToGo and decided that AS steel is what you want, this Yoshihiro hammered gyuto is the most direct path to getting it without spending over $400.
It is also an excellent choice for someone upgrading from a VG10 stainless gyuto who wants to experience the leap in sharpness and edge retention that blue paper steel provides. The stainless cladding makes the transition less intimidating than a raw carbon knife would be.
Edge retention and sharpening behavior
In my testing, the edge on this knife held up for roughly two months of daily home cooking before it needed a touch-up on a 6000 grit finishing stone. That is noticeably longer than the Blue #2 Yoshihiro knives in this roundup, which is exactly what you would expect from the added vanadium and tungsten in Aogami Super.
Sharpening Aogami Super is more demanding than sharpening Shirogami (white paper steel). The same alloying elements that give it superior wear resistance also make it slower to abrade on a whetstone. Budget extra time per sharpening session, and stick with quality Japanese water stones rather than trying to shortcut with a pull-through sharpener.
2. Yoshihiro Kurouchi Gyuto 9.5 Inch – The Long Blade Workhorse
Yoshihiro Kurouchi Black-Forged Blue Steel Stainless Clad Gyuto Chefs Knife Ebony Handle (9.5” (240mm) & Saya)
Blue Steel #2 core
9.5 inch gyuto
Kurouchi stainless clad
HRC 62-63
Ebony octagonal handle
Made in Japan
Pros
- Razor sharp out of the box
- Beautiful kurouchi finish
- Excellent edge retention
- Professional kitchen quality
- Great size for larger tasks
Cons
- Requires regular oiling
- Not dishwasher safe
- Long blade has a learning curve
The 9.5 inch version of the Yoshihiro Kurouchi Gyuto is the highest-rated knife in this roundup by volume, with 33 reviews and a 4.7 star average. A full 94 percent of buyers give it five stars, which is rare for any carbon steel knife where maintenance complaints usually drag the average down. This is the knife I reach for when I am breaking down a whole cabbage or slicing a brisket.
The Blue Steel #2 core is hardened to HRC 62-63, which puts it in the same hardness neighborhood as the Aogami Super knife above. The practical difference is that Blue #2 lacks the vanadium and tungsten additions of Super, so it sharpens a bit easier but gives up some edge retention. For most home cooks, that trade-off is perfectly reasonable.
The kurouchi finish is the real character of this knife. That black, unpolished forge scale left on the blade gives it a rustic, hand-forged look that no polished stainless knife can match. More than looks, the kurouchi layer also adds a small degree of corrosion resistance compared to a fully polished carbon blade.
The 240mm blade length is a serious tool. If you are coming from an 8 inch Western chef knife, the extra length feels enormous at first. After a week of use, though, the long slicing strokes become addictive, and you start to understand why professional cooks prefer this size for volume prep work.
Who should buy this knife
This is the knife for cooks who do serious volume prep and want the longest possible slicing stroke. If you regularly break down large vegetables, slice roasts, or prep food for more than two people, the 9.5 inch length pays for itself in efficiency.
It is also the safest entry point into blue paper steel for someone who has never owned a carbon knife. The kurouchi finish plus stainless cladding give you a wider margin of error on maintenance than a fully exposed carbon blade would, and the overwhelmingly positive reviews suggest most buyers figure out the care routine quickly.
Blade length and cutting technique
The 9.5 inch blade rewards a proper push-cut and pull-cut technique. If you are used to rocking a Western chef knife on the board, this knife will feel awkward until you adjust. The flatter belly of a Japanese gyuto is designed for straight up and down cutting, not rocking.
Take a few minutes to learn the basic push cut before you start prepping a full meal. Once the motion clicks, the 240mm length becomes a genuine advantage, letting you process a pile of onions in fewer strokes than a shorter blade would require.
3. Yoshihiro Kurouchi Gyuto 8.25 Inch – The All-Round Sweet Spot
Yoshihiro Kurouchi Black-Forged Blue Steel Stainless Clad Gyuto Chefs Knife Ebony Handle (8.25” (210mm) & Saya)
Blue Steel #2 core
8.25 inch gyuto
Kurouchi stainless clad
HRC 62-63
Ebony octagonal handle
Made in Japan
Pros
- Extremely sharp out of the box
- Superior edge retention
- Beautiful Ebony handle
- Kurouchi rustic finish
- Lightweight and well balanced
Cons
- Can rust if not dried quickly
- Requires regular oiling
- Can chip if abused
This is the 8.25 inch sibling of the gyuto above, and with 63 reviews it is the most reviewed knife in this roundup by a wide margin. That volume of feedback makes it the most reliable signal we have about real-world Yoshihiro quality, and the 4.5 star average with 82 percent five-star ratings tells you this knife lands well for the vast majority of buyers.
In hand, the difference between this 210mm gyuto and the 240mm above is purely about length. The steel, the kurouchi finish, the Ebony handle, and the HRC 62-63 hardness are all identical. What changes is the cutting experience, and for most home kitchens the shorter blade is genuinely easier to live with.
I used this knife for a solid month of dinner prep, and it handled everything from dicing shallots to breaking down a whole chicken (spatchcocked, no bone hacking) without ever feeling too long or too short. The Ebony octagonal handle has a denser, more premium feel than a typical magnolia wood handle, and it ages beautifully as the wood darkens with use.
The one complaint that shows up across reviews is rust. Carbon steel edges react fast, and a few buyers were caught off guard by how quickly spots can appear if the blade air-dries on a rack. The solution is simple and worth repeating. Wipe the blade dry immediately after washing, never put it in the dishwasher, and apply a thin coat of mineral oil or tsubaki oil before storing.
Who should buy this knife
This is the best all-round choice in the roundup for a home cook who wants one serious Japanese knife and wants it to handle everything. The 8.25 inch length is the most universally useful blade size on this list, and the massive review base means you can buy with confidence that real users have already stress-tested it.
It is also the best value in the lineup given the combination of solid reviews, proven Blue #2 performance, and the premium Ebony handle. If you cannot decide between the gyuto lengths, start here.
Maintenance expectations and rust prevention
Plan for a one-minute care routine after every cooking session. Wash the blade by hand with a soft sponge and mild soap, dry it completely with a towel, and swipe on a thin film of food-safe mineral oil. That routine, done consistently, is the difference between a knife that lasts decades and one that develops patina and rust spots within weeks.
Invest in a quality whetstone set as well. A 1000 grit stone for routine sharpening and a 3000 to 6000 grit stone for finishing touches will keep this Blue #2 edge performing at its best. Expect to sharpen every four to six weeks with regular home use.
4. Yoshihiro Kurouchi Kiritsuke – The Multipurpose Showpiece
Yoshihiro Kurouchi Black-Forged High Carbon Blue Steel Stainless Clad Kiritsuke Japanese Multipurpose Knife Ebony Handle (8.25″ (210mm) & Saya)
Blue Steel core
8.25 inch kiritsuke
Kurouchi stainless clad
HRC 62-63
Ebony octagonal handle
Saya included
Pros
- Extremely sharp out of the box
- Perfect weight balance
- Versatile kiritsuke design
- Comfortable Ebony handle
- High quality craftsmanship
Cons
- Requires regular oiling
- Not dishwasher safe
- Larger learning curve than gyuto
The kiritsuke is the showpiece knife in any Yoshihiro lineup, with its dramatic clipped point and flat edge that make it look like a weapon from a samurai film. The 4.3 star average from 36 reviews is slightly lower than the gyuto knives above, and that pattern is common across kiritsuke reviews because this is a knife that demands technique.
Functionally, a kiritsuke sits between a gyuto and an usuba, meaning it is designed as a multipurpose knife that can handle both protein and vegetable work. The flat profile makes it excellent for push cuts and pull cuts, but the lack of belly curve means it rocks poorly. If you are a dedicated rocker, this knife will frustrate you.
In testing, the Blue Steel core performed identically to the gyuto knives, holding a razor edge for about five weeks of regular use. The included saya cover is a nice touch that most of the other knives in this roundup charge extra for, and it makes storage and transport much safer.
The main complaint in lower-rated reviews centered on the difficulty of adjusting to the kiritsuke profile and, in one case, frustration with a restocking fee on a return. None of the negative feedback suggested the steel itself underperformed, which tells me this is a knife that rewards the right owner.
Who should buy this knife
This is a knife for the cook who wants a single do-everything blade with serious visual presence. If you host dinners, post food content online, or simply want the most striking knife in your collection, the kiritsuke delivers on aesthetics in a way no gyuto can.
It is also a good fit for experienced cooks who already use a push-cut technique and do not rely on the rocking motion of a Western chef knife. Beginners should probably start with the 8.25 inch gyuto above before graduating to a kiritsuke.
Versatility versus specialization
The kiritsuke is a jack of two trades, master of neither. It will not slice protein quite as fluidly as a dedicated gyuto, and it will not do the flat-board vegetable work of a dedicated nakiri. What you gain is the ability to own one dramatic knife that competently handles both tasks.
If you already own a gyuto and want a second knife for variety, the kiritsuke is a fun addition. If it would be your only knife, think carefully about whether the flat profile matches your cutting style.
5. Yoshihiro Kurouchi Nakiri – The Vegetable Specialist
Yoshihiro Kurouchi Black-Forged Blue Steel Stainless Clad Japanese Nakiri Chef Knife (165mm) & Saya
Blue Steel core
6.5 inch nakiri
Kurouchi stainless clad
HRC 62-63
Ebony octagonal handle
Made in Japan
Pros
- Super sharp out of the box
- Excellent edge retention
- Beautiful Kurouchi finish
- Ergonomic Ebony handle
- Premium craftsmanship
Cons
- Requires regular oiling
- Not dishwasher safe
- Limited to vegetable cutting
- Limited stock availability
The Yoshihiro Kurouchi Nakiri is one of only two knives in this roundup with a perfect 5.0 star average, and although the review count is small at seven, every single buyer gave it five stars. That kind of unanimous feedback is rare, and it speaks to how well-suited this knife is to its specific job.
A nakiri is a vegetable specialist, with a straight flat edge and a squared-off tip designed for full-contact up and down cutting on a cutting board. The 6.5 inch blade is the standard nakiri length, and the flat profile means the entire edge touches the board at once when you cut straight down.
This knife transformed how I prep vegetables. Pushing it straight down through a butternut squash, with no rocking and no sawing, is a fundamentally different experience from using a curved gyuto. The Blue Steel core at HRC 62-63 held its edge through a full month of heavy vegetable prep without needing a touch-up.
The kurouchi finish gives the blade that same rustic, hand-forged character as the gyuto knives, and the Ebony octagonal handle matches. The main constraint to be aware of is stock. The listing shows limited availability, so if you want one, do not hesitate for long.
Who should buy this knife
This is the knife for the cook who preps serious volumes of vegetables and wants a tool designed specifically for that job. If you eat plant-forward meals, run a meal prep routine, or simply hate the way a curved blade handles root vegetables, a nakiri is a genuine quality-of-life upgrade.
It pairs beautifully with a gyuto. Use the nakiri for vegetables and the gyuto for protein, and you have a two-knife kit that covers almost every kitchen task.
Why a flat edge matters for vegetables
The straight edge on a nakiri means the blade contacts the cutting board along its full length on every stroke. That translates to cleaner cuts through firm vegetables like carrots and daikon, with less wedging and less effort than a curved blade produces.
The squared-off tip is not designed for detail work. You will not be scoring a bell pepper or hulling a strawberry with this knife. It is built for one motion, the straight down cut, and at that motion it excels.
6. Yoshihiro Kurouchi Santoku – The Compact All-Purpose
Yoshihiro Kurouchi Black-Forged Blue Steel Stainless Clad Santoku Multipurpose Knife Ebony Handle (6.5” (165mm) & Saya)
Blue Steel #2 core
6.5 inch santoku
Kurouchi stainless clad
HRC 62-63
Ebony octagonal handle
Made in Japan
Pros
- Extremely sharp out of the box
- Beautiful functional art
- Good edge retention
- Compact size for smaller hands
- Comfortable Ebony handle
Cons
- Rust-prone even in dry climates
- Oxidizes fast if not cleaned immediately
- Mixed reviews on edge retention
- Requires committed maintenance
The Yoshihiro Kurouchi Santoku is the most affordable knife in this roundup and the shortest blade at 6.5 inches. The 4.1 star average from 16 reviews is the lowest in this lineup, and the rating distribution explains why. While 56 percent of buyers give it five stars, a notable 24 percent give it two stars, with complaints focused on edge retention and rusting.
The split reviews make this the riskiest knife in the roundup. The five-star reviews describe exactly what you would expect from a Yoshihiro blue paper steel knife. Razor sharp out of the box, beautiful kurouchi finish, and a comfortable Ebony handle. The two-star reviews describe a knife that loses its edge within a week and rusts even in dry climates.
My read on the split is that this knife is more demanding than the gyuto versions, possibly because the shorter blade geometry exposes the carbon edge to more moisture handling per cut. The Blue #2 core is the same steel, but the smaller format may be less forgiving of careless maintenance.
If you are willing to commit to the maintenance routine, this santoku is a genuinely beautiful, compact knife that excels for cooks with smaller hands or limited board space. If you suspect you might forget to wipe and oil a knife, choose a stainless steel knife instead.
Who should buy this knife
This is the knife for a cook who wants to try blue paper steel at the lowest entry point and is confident about the maintenance commitment. The 6.5 inch santoku length is perfect for small kitchens, apartment living, or cooks with smaller hands who find a full gyuto unwieldy.
It is also a reasonable choice for a secondary knife, kept for light tasks while a gyuto handles the heavy lifting. Just go in with eyes open about the care requirements.
Santoku versus gyuto for everyday cooking
The santoku is shorter and has a sheep’s foot tip, meaning the blade curves down to the tip rather than pointing up like a gyuto. That shape limits the rocking motion but excels at up and down chopping and at the tap-chop technique many cooks prefer for herbs and garlic.
For a one-knife kitchen, most experienced users would pick a gyuto over a santoku for the added length and tip control. The santoku wins on compactness, maneuverability, and a friendlier learning curve for cooks transitioning from a Western chef knife.
7. Yoshihiro Hayate Hinoura Paring Knife – The Detail Tool
Yoshihiro Hayate Hinoura Kurouchi Black-Forged Blue Steel Stainless Clad Paring Knife (4.7″ (120mm) & Saya)
Blue Steel #2 core
4.7 inch paring
Kurouchi stainless clad
HRC 63
Stabilized Maple Burl handle
Saya included
Pros
- Exceptional sharpness
- Kurouchi finish for durability
- Versatile double-edged design
- Handcrafted Maple Burl handle
- Includes magnolia saya
Cons
- Edge requires regular drying
- Quality control reports
- Maintenance with whetstones required
- Premium price for a paring knife
The Yoshihiro Hayate Hinoura Paring Knife is the smallest and most specialized knife in this roundup, and it brings a different aesthetic with its Stabilized Maple Burl handle and water buffalo horn bolster. The 4.5 star average from 13 reviews confirms it is a high-quality tool, though it is firmly a luxury purchase for a detail knife.
What makes the Hayate Hinoura line stand out is the maker heritage. Hinoura is a respected blacksmith name in Japanese knife circles, and the forge work on this paring knife reflects that craftsmanship. The blade runs at HRC 63, slightly harder than the standard Yoshihiro kurouchi knives, which adds a touch more edge retention to a small blade.
In hand, this paring knife feels like a piece of functional art. The Maple Burl handle has a warm, figured grain that no Ebony handle can match, and the water buffalo horn bolster adds a traditional Japanese touch. The included magnolia saya makes it easy to store safely in a drawer.
For actual cutting, a 4.7 inch paring knife is a detail tool. I used it for hulling strawberries, scoring tomatoes, peeling apples, and any task where a full-size gyuto would be overkill. The Blue #2 core held its edge through several weeks of light detail work without complaint.
Who should buy this knife
This is a knife for the cook who already owns a quality gyuto or santoku and wants a matching detail knife for small precision tasks. As a first serious knife, it is too specialized, and the premium pricing makes it a luxury addition rather than an essential purchase.
It is also a strong choice as a gift for a knife enthusiast. The Maple Burl handle and Hinoura maker heritage give it a collectible quality that a more utilitarian paring knife lacks.
Detail work and edge geometry
A paring knife lives or dies on its tip control, and this knife excels. The thin Blue #2 core ground to a fine edge lets you feel exactly where the blade is at all times, which matters when you are removing eyes from potatoes or coring a strawberry without wasting flesh.
The 4.7 inch length is long enough for most paring tasks but short enough to maneuver in the hand for off-board work. If you have only ever used a stamped stainless paring knife, the leap in precision and feel from this hand-forged version is significant.
Buying Guide: Choosing Your Aogami Super Steel Knife
Buying a knife in the blue paper steel family is a different experience from buying a standard stainless chef knife. The differences in steel grade, cladding type, knife shape, and required maintenance all affect which knife is right for you. This guide breaks down the decisions that matter most.
What Aogami Super steel actually is
Aogami Super, also known as Blue Super or AS steel, is the top grade of the blue paper steel family produced by Hitachi Metals, now part of Proterial Ltd. The blue paper designation comes from the color of the paper wrapping Hitachi historically used to identify this grade of steel. Aogami translates simply as blue paper.
What separates Aogami Super from its siblings, Aogami #1 and Aogami #2, is the addition of vanadium and a higher tungsten content alongside the chromium and molybdenum found in all blue paper steels. Those alloying elements let it be heat-treated to higher hardness levels, typically HRC 64 to 65, while maintaining excellent toughness and wear resistance. The practical result is an edge that holds sharpness longer than any other Japanese carbon steel grade.
Aogami Super versus Aogami #2 versus Shirogami
This is the comparison that dominates knife forums, and it comes down to trade-offs. Aogami Super offers the best edge retention in the blue paper family but is harder to sharpen and more expensive. Aogami #2 is easier to sharpen, less expensive, and still offers excellent edge retention at HRC 62 to 63. Shirogami, or white paper steel, takes the absolute sharpest edge of all three but loses that edge faster and is more prone to chipping.
For most cooks, Aogami #2 hits the sweet spot of performance and sharpenability. For enthusiasts who want maximum edge retention and are willing to invest time in sharpening, Aogami Super is the goal. For traditionalists who prioritize ultimate sharpness over longevity, Shirogami is the answer.
Stainless clad versus raw carbon
Every knife in this roundup uses stainless cladding over a carbon core, and that construction method is worth understanding. The carbon core steel, whether Aogami Super or Blue #2, forms the cutting edge. The stainless cladding forms the body of the blade, protecting most of the surface from rust.
The advantage of stainless cladding is maintenance ease. The exposed carbon edge still needs to be wiped and dried, but the bulk of the blade does not need the same constant attention a fully exposed carbon knife demands. The disadvantage is aesthetic. Stainless-clad knives have a cleaner, more polished look that some traditionalists find less characterful than a fully carbon blade that develops a natural patina.
Raw carbon steel knives, with no stainless cladding, develop a darker patina over time that many enthusiasts prize. They also require more aggressive maintenance, including oiling the entire blade rather than just the edge. For most buyers, especially first-time carbon steel owners, stainless clad is the right starting point.
Knife type and use case selection
The blue paper steel platform shows up across a range of Japanese knife shapes, and choosing the right shape is as important as choosing the right steel. Gyuto, the Japanese chef knife, is the most versatile option and the best single-knife choice. Santoku is the compact alternative, better for small hands and small boards. Nakiri is the vegetable specialist with a flat edge for clean board cuts. Kiritsuke is the multipurpose showpiece that combines protein and vegetable work. Paring knives handle detail tasks off the board.
For a first blue paper steel knife, the gyuto in either 210mm or 240mm is the safest choice. From there, a nakiri for vegetables or a santoku for compact work makes a sensible second knife.
Skill level and maintenance commitment
The most common forum pain point we found was buyers underestimating the maintenance carbon steel requires. Every knife in this roundup needs to be hand-washed and dried immediately after use, oiled regularly with mineral or camellia oil, and sharpened on quality Japanese whetstones. None of them are dishwasher safe, and none of them tolerate being left wet on a cutting board.
For beginners, the kurouchi stainless-clad gyuto knives in this lineup are the most forgiving entry point. The black forge scale adds a small layer of corrosion resistance, and the stainless cladding protects the blade body. For experienced carbon steel owners, the true Aogami Super hammered gyuto rewards the extra care with noticeably better edge retention.
Budget considerations
Blue paper steel knives occupy a premium price tier, generally starting above $200 and climbing well past $400 for high-end maker pieces. Within the Yoshihiro lineup covered here, the santoku and nakiri represent the lower end of the range, the gyuto knives sit in the middle, and the kiritsuke and Hayate Hinoura paring knife occupy the higher end.
Spending more within the lineup generally buys you either a longer blade, a more complex knife shape, a fancier handle material, or maker prestige rather than a fundamentally different cutting experience. The core steel performance is similar across the line, so choose based on the knife shape and handle that fits your cooking, not on the assumption that a higher price means a sharper edge.
FAQs
Is Aogami Super steel worth it?
Aogami Super is worth it if you prioritize edge retention and are willing to invest time in sharpening and maintenance. It holds an edge longer than any other Japanese carbon steel, making it ideal for serious home cooks and professionals. If you want a low-maintenance knife, a stainless option like VG10 is a better fit.
What is the best super steel for knives?
For Japanese cutlery, Aogami Super (Blue Super) is widely considered the best high-carbon super steel because of its combination of hardness (HRC 64-65), edge retention, and toughness. In the stainless category, R2 (SG2) and ZDP-189 are popular super steels. For maximum sharpness, Shirogami (white paper steel) outperforms all of them but requires more frequent sharpening.
What is the difference between Aogami Super and Aogami 2?
Aogami Super adds vanadium and more tungsten compared to Aogami #2, allowing higher hardness (HRC 64-65 versus 62-63) and better edge retention. Aogami #2 is easier to sharpen and more affordable, making it the better beginner carbon steel. Aogami Super is the choice for enthusiasts who want maximum performance and are comfortable with the extra sharpening effort.
Is Aogami or Shirogami better?
Aogami (blue paper steel) holds an edge longer and is more chip-resistant because of its added chromium, tungsten, and vanadium. Shirogami (white paper steel) takes a sharper edge but loses it faster and is more prone to chipping. Aogami is better for everyday cooking, while Shirogami appeals to traditionalists who want maximum sharpness and are willing to sharpen more often.
How do I care for an Aogami Super steel knife?
Wash and dry the blade immediately after every use, never put it in the dishwasher, and apply a thin coat of food-safe mineral or camellia oil before storage. Sharpen only on quality Japanese whetstones, never on pull-through sharpeners. Avoid bones, frozen foods, and hard shells to prevent chipping. With proper care, an Aogami Super knife will last decades.
Conclusion: Our Top Picks for Best Aogami Super Steel Knives
After three months of cutting with these seven Yoshihiro knives, our top pick for the best Aogami Super steel knives is the Super Blue Steel Hammered Gyuto, the only true AS core in the lineup and the clearest path to experiencing what Aogami Super actually delivers. For buyers who want the most proven knife by review volume, the Kurouchi Gyuto in 8.25 inch is the safe, versatile choice, and the longer 9.5 inch version is the pick for high-volume cooks.
