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 from handle to 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 0.00045 micron mirror finish of the blade in ZDP189 steel at 67 HRC and you have a winner combo. The hardness of the knives may vary slightly, but the exact hardness measured precisely to a 10^th of a Rockwell is visible on the certificate accompanying the knife (Rockstead tests each knife individually. The shape of the Ryo is based 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 in the hand 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. This is the blue version.

The Ryo has a total length of 196mm. The blade is 80mm with a thickness of 3.2mm. It weighs 124 grams.
