about six years ago i got into grinding some blades and heat treating. i bought an anvil and hammered out a crude camp knife. then i got too busy, moved and never made another blade. well the bug hit me again and i set up my forge last night. now i have some questions. my only hammer is a swedish pattern. what other hammers do i need (bear minimum)? what is the best design tong for holding thin metal stock for blade making..V...flat..other?
