I'm with you moral, how the hell does he do what he does with his hand like that?
Several years ago I tried to get more spin in real life on my forehand so of course I tried to copy rafa in some way humanly possible for me. The thing I noticed I could copy was the fact he doesn't hold a fist on his forehand. He holds the racket with only his 3 bottom fingers and his thumb. His index finger is seperated and points up and raps around the handle diagonally.
I did it and it worked for me. Of course it only works with small size handles. In the beginning I had a hard time gripping the racket(understandably). My index finger got some scraps at the beginning but then I learned through experience how to avoid that.
Long story short one day I ripped the bottom of my ring finger's skin. It was disconnected on 3 sides and I could flop it back in place or let it hang the opposite side, it was gross. I did figure out afterward I put on a new overgrip which really did it's job not allowing the racket to slip. Also that day I swung a little harder. The skin ripped on just one hard shot.
Rafa hits thousands of balls, the ball is being hit much harder at him, he can of course swing way harder than me, his overgrips are always new and have virtually no slip, and he's using that 10.5 oz racket. How does he have any skin on the inside of his left hand?

The magic of finger tape

. But there is so much friction he gets blisters through the tape. And how he got it in the middle of his hand I don't know. A new place for finger tape.
P.S. I use finger tape on my middle and ring finger now just to be safe
