After seeing some antique push daggers in one of my gun reference books I decided to make one from some 1/4'' steel plate I cut from an old trailer hitch I replaced on a vehicle at work. I cut the rough shape out with an angle grinder, ground it to shape with my 7'' disc grinder. Used a 6'' DA (orbital) sander to finish and then hand polished it with MAAS metal polish and an old t-shirt. Tempering was not necessary since it is a stab weapon, not for cutting. The scales are oak, attached by 3M double sided tape. It was fun to make.
