I've got a couple of pairs of Gilded Age jeans that I love, but they have giant crazy exposed rivets- serious spires of homicidal copper that stick out a good 3-4mm+. They catch my hands as they go in the pockets, and threaten to scratch all hard surfaces they touch. Not a big deal, but for whatever reason, it irks me. Now, I'd imagine I can just use something solid as an anvil (to rest the rivet's back on) and give a good whack with a hammer to flatten, but I'm not aware of the way these sorts of rivets are constructed. If the center spike is made of solid metal, it may just mushroom nicely- if it's hollow, it'll probably split and get even sharper. Either way, I risk cracking the surrounding piece, and then it's all for naught. Has anyone done this? How'd it turn out?
