Practicing hands. Machete has quite bony and feminine ones with long fingers and tidy claws.
I'm not sure why he wears ribbons or bandages on them, really. He originally had his hands/front paws chopped off and replaced with prosthesis and bandages were used to keep them firmly in place, but I've ditched that idea long ago. I guess they're there just for extra protection? Of course they could prevent him from accidentally cutting himself with his knives and daggers when handling them.
Marker and Gimp.
