Been playing with my new tools. It was either, "Why did I wait so long to buy them?" or "What's all the fuss about?"
Thankfully, it's the former not the latter. I'm glad I didn't replace my chain-nose or bent-nose pliers...the original ones I got from the late(?) great Bead Biz of El Cerrito are wonderful.
But my new, teeny-cone round-nose pliers have already paid for themselves. I still have my original round-nose pliers, and they're great for tasks such as creating the loops in earring wires, where you need larger cones. If you're going to make the kind of headpins that have a tiny loop at the bottom, you might want to invest in pliers with teeny cones.
