I decided after a lot of back and forth against knife edge for a P4
Kinda glad I did, I don’t think life edge would hurt but I do think you’d feel it more
There’s a lot of stuff going on underneath the wrist, it’s probably best to avoid or REALLY do your research and get an installer who knows that area
(A defensive thing that’s taught these days is, when taking a melee defensive stance, try to roll the under sides of your arms inwards, as they are contain the large arteries and other good stuff, and the outside of your arm is mostly flesh and muscle… much better to sacrifice)
