ROCKSTEAD RYO H ZDP 189 BLUE

The Ryo, which is Japanese for “Good”, is a very unique everyday carry knife. It stands out for a number of reasons. First, the blade. It utilizes the Rockstead ‘Honzukuri’ style blade, where it has been sharpened is such a way that it is convex, while gradually getting thinner towards the tip. And all this without a micro bevel. Rockstead believes this is the ultimate shape and geometry for cutting tasks. Combine that with the smooth mirror finish of the blade and their ZDP189 steel, produced with nanotechnology to achieve a hardness of around 67HRc and you have unbelievable edge retention. The hardness of the knife may vary, but the exact hardness is visible on the certificate accompanying the knife (Rockstead tests them individually. The shape of the Ryo is base on traditional Higonokami knives, which are very common Japanese pocket knives, often handed out at schools to sharpen pencils. Second, the Ryo has a hide-away pocket clip. Pocket knife users sometimes dislike pocket clips, because it doesn’t feel comfortable when using them. The pocket clip of the Ryo can slide away into the handle, so you don’t feel it while cutting. The handle itself is made of titanium, which has been DLC (diamond like carbon) coated. The Ryo has a total length of 196mm. The blade is 80mm with a thickness of 3.2mm. It weighs 124 grams.
