The only one I've seen that looked like it would stand any effective use was from the BSA in the late 70's/early 80's. It was single strand wire with teeth formed from the wire. The gauge was heavy enough that it had to be rolled & the teeth were aggressive to the point that you kept the plastic bag it came in to store it & even then it poked through.
I remember having one of those. The teeth were indeed pretty wicked, and would quickly destroy whatever container it was stored in, and then start tearing up whatever it was packed next to.
