Smith's Top and Bottom Tools: Punch, Drift, Hardy, Fullers, Chisel and Swage
Bottom tools have a square shank that drops into the anvil's hardy hole; top tools have a handle and are held on the work and struck. The hardy cuts hot stock laid over it, the fuller's rounded nose spreads metal, the punch makes a hole and the drift opens it to size, the hot chisel cuts from above, and the bottom swage rounds bar in its groove. Forge them all from tool steel.
