Czeck Edge offers a Kit for every Production Tool we manufacture (Some Carbide Tools and Ruler Stop excepted). Each Kit contains a ready to install production blade, ferrule (ring type, unless noted) and instructions. These Kits give the craftsman the satisfying opportunity to produce a professional grade tool with a handle made to their specification. No metal working experience or equipment is required. Also, the inherent dangers and pitfalls of heat treating and precisely shaping small metallic parts may be avoided.
