So you ask for documentation, I provide it, and then your forty years of experience trumps the manufacturers engineering and experience and the UL testing. Got it. If would have let me know "because I said so" was the basis of your position I wouldn't have wasted my time.
Greenlee, the maker of that stripper, does not make wire or connectors. Southwire and Ilsco, the manufacturers of the wire and connectors does not make that style of strippers. It's collusion though...
The drawing is the sheet I received in my last order of cpm adapters.
I don't know the answer as to how many people actually do it the right way. I know Rosedin Electric doesn't allow knives for stripping, which means their guys don't even have a choice in the matter. They're a small outfit doing equally small projects.
You're right, you could probably do just as good of a job freehanding it as my tool. The only difference is the stripper I have is repeatable no matter whose hands the tools is in.
