I'm looking for as many words (and corresponding definitions) as I can find for different specific types of leatherworking. Archaic words are fine, even preferred. Of particular interest is a single word for repairs performed by cutting away damaged areas and stitching together with lanyard, if available. I'm looking for words related to leather crafting and repair, not so much production.
Multi-word terms that aren't specific to leatherwork or may only be read as specific to leatherwork in context (like "rip work" for the specific term I describe above) are probably not useful to me.
