@laumapret @sinituulia I've bought some cheap cutters from the hardware store designed to cut steel wire, and they make a big difference in how easy dealing with spiral steel boning is, even if they are very much not top of the line tools or anything.
for flat steels I still tend to use a dremel-like power tool (or ideally, get somebody else to use a dremel for me :D ) to cut and sand down the edges, but that's helped by the fact that we do have such a tool at home for various other reasons
I'm still using the two regular pliers and lots of cursing (the latter is an integral part of the procedure, right?) for the end caps, because being multicraftual (in a multicraftual household) means that we have lots of multipurpose tools, but I don't do enough corsets to justify yet another single purpose one.
