Interesting. I never investigated, sort of just thought it was a spelling error that turned into a trademark.
Yeah its pretty vicious, some brands and qualities are worse than others. Modern cable tends to have the jacket welded to it very tightly so you need to skin the whole thing in one go, while older cables you can peel the jacket off, then work on the ternplate by itself. It's very satisfying to start a cut and push it through the metal.
I have almost abandoned my splicer knife. It's either too sharp and cut a pair while I ring the cable, or too dull and I cant effectively skin it. A hook blade razor almost never fails
