Hi all, I'm desperate to find a pair of pliers or an easier way to make a 1/2" hole in 4-6 oz leather. I have the Osborne hand held punch that you whack with a mallet, but it's slowly killing me with how many holes I need to make. I've tried a hand press and hole making dies, but it won't go through my leather, and i can't find dies the right size anyway... Any suggestions?
