Rockstead RYO H-ZDP (DP) Folding Knife 80mm
Since its inception over 70 years ago, Rockstead Knives have been producing unique and extremely high performing fixed and folding knives. Rockstead specializes in unorthodox manual machining practices and modern materials to output knives that create a league of their own.
The RYO is a beautiful, functional, and rugged offering from Rockstead. Featuring Rockstead’s high performing compound “zero grind” (HONZUKURI) made of ~66 HRC ZDP-189, the RYO makes use of a flat edge profile, sometimes called sheepsfoot, reverse tanto, or Higonokami style blade shape. The 3” blade lends itself best to utility cutting tasks, with its downwards pointing tip.
The titanium handle scales are milled to enhance the grip in hand, and to beautifully allow light to roll over the ridges. On the show side, the milled waves are uninterrupted, as the knife makes use of hidden hardware. Hiding within the spine of the handle is the patented clip system of the knife, that tucks into the handle, in order to eliminate the ergonomic hot-spot a clip may present.
The RYO, meaning ‘good’ in Japanese, undersells what this knife is. The handle is ergonomic, innovative, and beautiful. The blade of the RYO is elegant, functional, modern, and has design cues from traditional Japanese folding knives. This knife represents some of the best that Rockstead has to offer, whether you are a folder carrier, enthusiast, or collector.
