Bladesmithing, Forging a Railroad Spike Knife: GunVenture|S1 E5 P3
This video demonstrates the process of bladesmithing a railroad spike knife. It covers heating the spike in a coal forge, shaping it on an anvil and in a vise to create a twisted handle design, and forming the blade. A key technique shown is differential heat treatment, where only half the blade is quenched to harden the edge while keeping the spine flexible.
