I'm sitting here cutting texsolve tie-up chords for my new-to-me 60 year old Swiss loom. I came up with a quick way to do it: I got old an old soldering iron, taped my ruller to the counter to do the measuring, and use the soldering iron to cut the texsolv and fuse the ends in one operation. My counter is stone, but you could use the bottom of a frying pan or maybe a cookie sheet if your counters are something that the iron would burn.
