Stub Twist refinished by Paul Stevens



Stub Twist was made from a 1:1 ratio of horse-nail stubs (iron and the supply of which was inadequate by the 1850s) mixed with chopped coach spring steel, fused ("puddled") into a "bloom of iron", then hammer forged or rolled into a rod.

Plain Twist was not "puddled"
