I was told many years ago about a tool for removing nails (not a claw
hammer).

A claw hammer is quite good for removing nails. Select the appropriate
finger and put it against a firm surface. Hit it firmly with the claw
hammer. Club hammers are naturally more effective and if you have a helper
a large sledge hammer is even better. ;-)

I found the drive gear on a cement mixer to be very effective for this
purpose :-0
