Last week, as I was cutting a batch of soap, my second-to-last guitar string broke. My daughter was in the kitchen when it happened. She makes jewelry and suggested the wire she uses to make earrings. Alas, it was too thick. She inherited my jewelry-making tools and supplies, so I also knew that in her bin was a spool of fishing line that I used to use to make necklaces. She brought the spool down and I connected it to my cutter, winding it as tightly as I could. It worked!!! The benefit of using this is that it doesn't kink, which is always what would lead to the wires breaking, and NO drag marks. Just a nice, smooth, even cut. And it can manage a LOT of tension. I have a single-bar cutter, so not sure how well this would work on a multi-bar cutter.
