When first learning a point, I might practice that way. Our approach invites a lot of experimentation within safe parameters. We wouldn't, for example, encourage people to experiment with sound and stances and the whole menu if the person didn't know the revivals and the basic material earlier in the curriculum. Safety needs to come first.
After the initial experimentation with a point, we play with different entries, different weapons. As you could expect, no little boney protrusion in my wrists is going to make much of a penetration in the flesh of a 250 lb male. The basic heart revival that we are taught, just for example, uses exactly that kind of a strike to UB 15 on the right side of the back. Master Gary Rooks taught me an alternative that works for me. I use the flat part of my fist making contact with the proximal phalanges and twisting. Since I have never done this actually on someone who's heart has really stopped, let me define "works" as striking in a way in which uke reports that he feels a bolt of electricity going through his chest.
The older I get, the better I was!
