A tool that I don’t use very often, but when I need it I’m glad of it, is my chenier cutter.
Chenier is fine hollow tubing, which can used to make various parts such as hinges and bails, or be used decoratively as I have in this ring:
To cut the chenier to the right length, and/or to file the ends of the chenier flat, it’s much easier to clamp it in this cutter.
The cutter has various spaces to cut at both 90 degree and 45 degree angles.
It’s great for cutting wire, too!
