Konosuke knives are known across the industry for exceptional quality, incredibly thin grinds, and flawless performance, and the HD line is consistently one of the most popular series CKTG carries. At 270mm, this sujihiki is ready for whatever a home cook or professional throws at it.
The blade is a mono steel construction using HD2 semi stainless steel, heat treated to about 61 HRC. The geometry here is built for high performance, with a spine that runs thin and an edge that gets insanely thin just behind the bevel, letting the steel take and hold a genuinely acute sharpening angle. The handle is ebony and laurel in a slim octagonal shape, and Konosuke installs it with a small intentional gap at the machi, a detail known as Tokyo style that traces back to when handles were burned into place rather than fitted with modern tolerances.
What Customers Are Saying:With six reviews, this sujihiki draws consistently high praise, with several buyers calling it the best knife in their collection and describing the out of box sharpness as exceptional, wafer thin at the edge, and a real pleasure to use even after owning other high end Japanese knives for years. One reviewer with larger hands would like to see a bit more height at the heel, and another suggests the choil could use a touch more rounding, both fair notes for anyone comparing this to other sujihikis in that size range.
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 given the length of this blade, store it where it will not knock against other tools in a drawer.

Out of the box this knife was amazingly sharp. It is wafer thin at the edge and drops right through what your cutting. The length was perfect as I prefer a larger knife. The balance point is right below the engraving so for a pinch grip it's spot on. The only thing about this k ice I would change is little more hight on the heel. I have larger hands and it would be more comfortable if there was more clearance between the handle and board.

All of the hype is real--this knife is brilliant. I wondered if the 270 might be a bit much, but this feels more nimble than my 240 Masamoto VG. The ootb sharpness was very good, and the knife is a delight to use.
