This blade outline is image the "HIGONOKAMI" which represent knife in Japan. And, blade shape is convex (HONZUKURI).
It is very easy to use and cuts well.
This handle material is titanium with DLC and blade material is ZDP189.
This greatest feature of this knife is its movable clip system, called the "concealed clip system". We have originally produced the concealed clip system to eliminates the uncomfortable feeling of the "clip feel" when gripping the handle. However, it turns out that a part of the mechanism of this "concealed clip system" conflicts with US patent Nos. 8,112,894 and 8,783,141.
We have been licensed to use these US patents after negotiations with Mr. Joseph Caswell, the US patent owner.
良 "RYO" in Japanese means "good".
