Been using the Beastmaker app for a while, nothing very difficult as still can't complete the 5a one all the way through, but had a flick through the others today and don't know what its talking about.
So: what is the difference between:
a) open hand
c) half crimp- no thumb involved.
All of these seem pretty much the same to me!
A google didn't help me but if I've just been blind feel free to link
I think a chisel is when you kind of bend the tips of your fingers outward at the first knuckle so you get a larger contact with your tips on the hold but you still get that nice bent main knuckle for strength, it's a bit of a weird one to be honest.
If I pull half crimp on a small enough hold it will tend to pull my fingers into a chisel anyway so you don't get much choice.
(I might be wrong by the way but that's my interpretation)
