Improved Knife Hands

Decided that I would try and fix the knife's ugly hands, I succeeded.

All this skin does is makes the default knife's hands a bit less odd, in the old comparison screenshot you can see that the arm goes 'into' the hand, literally, so I decided to improve/fix it by changing the rigging a bit.

I also tweaked with some other stuff in order to make it look a bit better.

Enjoy!
