Swedge

Refers to a chamfer on the back of a blade. A “common” swedge begins gradually with a long taper, whereas a “cut” swedge begins with a small shoulder and then tapers on out to the blade point. A “single” swedge means one side only – the mark side, and a “double” swedge means both sides. A “long” swedge begins at, or close to, the blade shoulder. In the cutlery trade, this word is commonly spelled “swedge” but is listed in dictionaries as “swage.” See: False Edge
