Czeck Edge offers a Kit for every Production Tool we manufacture (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 and the danger and pitfalls of heat treating and precisely shaping small metallic parts may be avoided.
