They need to make a splitting wedge with a replaceable high molecular polyethylene head (fiskars used to make one with some kind if plastic head) so you can hit it without worry and you wouldn't need hearing protection to comfortably use it. Or reinvent technology from a hundred years ago and put a socket at the head of the wedge so it would accept a
Wooden striking surface. Then you could replace the wood as needed (not as often as one would imagine if my sources are telling the truth). I'd buy an antique one if I could find one. I suppose a wedge that would last forever and not need replaceable plastic parts would be bad for business.
The POS Indian wedges mushroom about as fast as they split. And of course I misplaced my grandfors in the move.
I've even considered making a big ol' Fred Flintstone maul with an elm head to drive wedges with. There just has to be something quieter, safer, and longer lasting than hard steel on soft steel.
