I have used a set like those for 20years to stretch wet rawhide onto drumbodies: I know that they were not intended for that,but I'll put my $$ on upholstery or farrier's tool.
Arainging your blacksmithing equipment to stash on a cart t hat can roll under cover for over night as well as theft deterrence may help.Try to avoid putting a hot forge in a small space. Wear your safety glasses. Be kind to living things, and Forge on!
