Xinguo’s Honyaki are special items in many ways, the look, the steel and even the maker and region of production. These blades are truly remarkable to look at, and I don’t want that statement to overshadow the performance of them. This ApexUltra Honyaki really stands up to this studio’s motto: Pursuit beyond high proficiency in forging and polishing, but seek strong expression in different products.

You might think the name ApexUltra doesn’t sound very Japanese, and it is indeed not. This is an alloy carbon steel developed by European and American metallurgists based on 52100 and Blue Super that aims to be the best available culinary carbon steel. It behaves like those two steel but has a much better performance in working hardness, edge retention and toughness at high hardness. It really makes Xinguo’s knives stand out as I don’t expect Japanese makers to pick up this new foreign steel any time soon.

ApexUltra is excellent in its hardness, with regular oil quench, it can reach 65 HRC easily, which you would have to push for with Blue Super, but Xinguo pushes this even further by performing a water quench rather than a safer and perfectly viable oil quench, because this steel need quicker quench to produce hamon. This brings the steel to its highest achievable hardness of 67-68 HRC, which is unheard of in the world of Honyaki. I’m not sure how they manage the failure rate but it is impressive to know something like this can be done. This hardness allows a very thin and fine edge to be put onto these Honyaki knives, combining with a quite well controlled convex grind, the cutting performance can go toe to toe with some of the Japanese counterparts that produce similar knives.

The appearance would be a totally different story, and I think Xinguo has achieved their goal of seeking strong expression with this knife. This surface of the knife is entirely covered by very strong alloy banding, and the fine glitter-like pattern has such a strong texture that makes me think of the legendary Wooz steel. This alloy banding is a phenomenon commonly found on alloy carbon steel especially those with a lot of Tungsten, but this is not common especially like this one with strong contrast. To intensify this look, the blade is etched to increase the contrast. The harmon turns to a light grey colour with brighter banding over it, but the hardened steel shows a light blue sheen, which looks breathtaking when paired with the mirror polishing and the white banding floating over it.

The knife takes a more Sakai style profile, but made a bit wider than typical, although Honyaki tend to be some of the more “collector items” this board blade with a pretty thin edge would still be happy to chop through whatever you feed to it. For head chefs and collectors, this line offers a reasonable option for you to experience a premium Hoyaki Ownership, but I say the price speaks very little about how well these blades are made, whether in terms of fit and finish, craftsmanship or overall design and aesthetics.

Pros Cons
  • Excellent performance
  • Great artistic
  • Excellent fit and finish
  • High budget
  • Prone to rust
Care Instruction
  1. Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
  2. Wash with neutral detergent after use, and wipe dry;
  3. Please don't wash knife with dishwasher, it will damage the wood handle;
  4. Be careful not to leave the knife close to a heat source for a long time;
  5. It is a lot more dangerous to cut with a blunt knife than a sharp knife!
  6. It is best to sharpen a Japanese knife regularly on a waterstone.
  7. Oil the (carbon) knife if storing for an extended period of time to prevent rust.

Xinguo, a knife workshop team near Shanghai

Xinguo (新國) is a small Chinese knife workshop team based near Shanghai, not a single maker. Xinguo says it founded the brand in 2016 and that a master craftsman leads its team of partners and apprentices. It says it forges water-quenched honyaki by the clay method (tsuchioki) as well as Western-style chef knives, and works with Shirogami, Aogami and Ginsan from Japan, MagnaCut and ApexUltra from the US, and RWL34 from Sweden. The team says it is still new to making knives and that support from knife enthusiasts motivates it to keep improving.

Xinguo began as a small group of hobbyist knifemakers who also repaired high-end Japanese knives, and in 2022 it set up its factory and moved into full-scale production. In that factory we saw a large contact wheel, custom-made to match a Japanese grinding stone, that the team uses to repair the hollow of single-bevel knives. The team also makes its own abrasives to give its knives a consistent finish, and its own diamond stone for the high-alloy powder steels it grinds.

Because Kisuke Manaka works alone and his output is limited, we asked Xinguo to sharpen and polish his blades. That arrangement produced the Kisuke x Xinguo line, which carries both names.

We list the Kisuke x Xinguo Blue 1 Damascus gyuto, the Aogami Super honyaki gyuto, the ApexUltra honyaki gyuto, and the Ginsan tsuchime honesuki with a guard.

Frequently asked questions

Gyuto or santoku: which should I choose?

Both are all-purpose Japanese knives, and for most home cooks either will handle the bulk of daily prep. The choice comes down to length, blade shape, and how you like to cut.

A gyuto is the Japanese chef's knife, with a gently curved edge that lets you rock and slide through cuts as well as chop. Tojiro's guide to Western knife shapes gives 150 to 210mm as the household size for a gyuto and up to 360mm for professional use. The extra length and pointed tip give you reach and versatility, from proteins to large produce.

Tojiro's guide to Japanese knife shapes gives 165 to 170mm as the household size for a santoku, which has a flatter profile and a rounded sheep's-foot tip. It rewards a straight up-and-down push cut, feels nimble in smaller hands or tight kitchens, and is the classic Japanese household knife.

Rule of thumb: choose a gyuto if you want one do-everything knife with more reach, or a santoku if you prefer a compact, easy-to-control blade. Plenty of our customers end up owning both.

What is a gyuto knife used for?

The gyuto (牛刀) is a chef's knife for all kinds of cooking, and it is basically double-bevel. A knife maker's guide says it came to Japan in the Meiji era with the culture of eating beef, which gave it its name, but it does not cut only meat.

A Japanese dictionary describes the gyuto as slimmer than a santoku, with a pointed tip, used widely for meat, fish and vegetables.

What gyuto length should I choose?

A knife maker's guide lists 150 to 210 mm, double-bevel, for home use, and 180 to 360 mm, single- or double-bevel, for professional kitchens.

We suggest starting with a 210 mm gyuto for a home kitchen, and stepping up to 240 mm if you regularly cut large pieces and have the board for it.

240mm vs 210mm gyuto: which size should I choose?

Get the 210mm. We only point people to a 240mm when they have about 45cm of usable board, cook in volume, and regularly break down big roasts or whole fish.

On the gyutos we've measured for our product pages, the extra length is real. As of October 2026, the 210mm gyutos we list have a median edge of 213mm from heel to tip, across the 111 we have measured; the 240mm ones have a median of 240mm, across 100. The 240s are also heavier, 212g against 175g at the median, and a touch taller at the heel, 50mm against 48mm.

That length buys you a longer stroke. A 240 goes through a big piece of meat in one or two pulls and moves a board of chopped vegetables with less shuffling. It costs you board space and control. On a small board the tip hangs off the edge, and fine work like herbs and shallots feels like more knife than the job needs.

Japanese or German kitchen knives: which should I buy?

Our advice: choose a Japanese knife if you want the keenest edge and do not mind caring for a harder blade, and a German knife if you want a tougher, more forgiving knife you can hone casually and use for heavy prep. On two Japanese knife steels, the steel makers' own figures start at 60 HRC: Takefu Special Steel rates VG10 at 60 HRC or more, and Proterial lists the hardening hardness of Aogami 2 (Blue 2) as over 60 HRC.

Our care advice for a Japanese knife: keep it off bone, frozen food and very hard squash, and use a wooden or plastic board.

What is the flat spot on a knife, and is it the same as the "sweet spot"?

The flat spot is the straight run of edge from the heel towards the middle, the part that meets the board along its length. At our counter we call it the sweet spot; elsewhere "sweet spot" often means the balance point, so ask which one someone means.

Past the flat, the edge curves up towards the tip (the belly), which suits a swinging or pulling stroke. Sharpeners also say "flat spot" for a worn patch of edge, so when you mean the shape, "the flat part of the edge" is clearer.

Is ApexUltra a carbon steel?

Yes. The ApexUltra site describes a low alloy design that is forgeable and forge-weldable, and offers it to anyone seeking the next level of performance in carbon steel knives.

The site says the fine carbides make the steel relatively easy to finish and sharpen, and that its forging and forge-welding can be described as similar to 52100 steel's. Like other carbon steels it can rust, so wash the knife after use and dry it.

What is ApexUltra steel?

Its own site calls ApexUltra a low alloy steel that is forgeable and forge-weldable, and describes it as a steel worthy of handcrafted knives.

The site names culinary knives, razors and carving knives as good applications, and credits the steel to Larrin Thomas, Marco Guldimann and Tobias Hangler.
