If not the best. If you cut a wire with these things, it looks like you're cheating. Because it runs so smoothly, you'd think you're cutting stupid putty. I checked out a YouTube channel where he compared a number of cutters. It was one of the best he showed. So I got the set. The first thing I did with them to see how good they were was cut from 1/8" stainless steel. I try as hard as most other aluminum cutting torches. In fact, I didn't think that it's rust free, I should have checked twice. If you're reading this, buy these. In fact, buy two. Because you know your neighbor will "borrow" the first set.
