This Konosuke HD2 gyuto is one of the most talked about lasers in the CKTG catalog, the blade other thin grinds tend to get measured against. The fit and finish are exemplary, as expected from Konosuke, but the real story is in the grind itself.
The core is HD2 semi stainless steel, hardened to about 61 HRC, with an ultra thin, subtly convex profile that drops through produce with very little resistance. The out of box edge earns the term razor sharp in the truest sense, and the whole knife is built around subtlety and simplicity rather than flash. Being semi stainless, HD2 is easier to care for than an equivalent high carbon steel, though it will still patina over time unless kept polished. This particular knife features a Khii laurel handle, sized and weighted to balance the blade well in hand.
What Customers Are Saying:Reviewers confirm the knife lives up to its reputation, describing it as light, perfectly balanced at the pinch grip, and a true beast through produce with excellent food release thanks to the grind. One reviewer notes the blade stained fairly quickly after vegetable prep, though the stain was easily removed and did not look unattractive, and also points out the profile does not have much of a flat area, so it suits a bit of rocking motion better than pure push cutting.
Care Instructions:HD2 is a semi stainless steel, easier to care for than a fully reactive carbon steel but not entirely rust proof, so hand wash and dry the blade after use rather than running it through a dishwasher. It will develop a light patina over time, or you can keep it polished if you prefer a brighter look. Avoid cutting through bones or frozen foods, and sharpen on quality water stones when the edge needs attention.

Everything in the description is accurate - this knife is a beast. Flies through produce, the 240mm is perfect as the blade is lighter than you think it will be. Razor sharp out of the box. Pretty patina resistant, but will still take one if you let it. Great food release due to the fantastic grind. It is perfectly balanced with a proper pinch grip. Can't recommend it enough. It is a little pricey, but absolutely worth it. I'm a knife addict and I haven't purchased another since I got this about 2 years ago.

This knife is gorgeous. It feels great and has decent food release. It stained very quickly after some vegetable prep but it isn't unattractive and could easily be removed. It does not have a very big flat area so I wouldn't recommend it for pure push cutting, but if you're up for adding a bit of a rock and a glide to your cutting action, you're in for a good time.
