The Ryo folding knife is an exciting model from Rockstead that features a Higonakami blade shape, which is based on the classic Japanese knife. It has a convex ground ZDP-189 steel blade and DLC "Prism" coated titanium handle. An innovative "concealed clip" on the Ryo eliminates discomfort associated with a regular pocket clip by retracting into the handle.
