I have never seen this tip, so I hope this will be helpful to someone at some point...
You know when you've got your locking pliers on the mandrel and you're trying to hold on to a bead so you can break the bead release and get the bead off? But the bead is small and slippery, and glass is hard stuff. It hurts my fingers.
I used to use one of those nonslip-rubber jar-lid thingies, but once it's wet, the friction reduces dramatically, and I'm always trying to twist wet beads so I don't inhale the bead release. So it's a hassle to dry the rubber thingy and/or the bead surface and try again.
Something that does work, fantastically, is just
paper towel! It grips, it has a little bit of cushion (extra nice if your bead has raised bumpies), and all I need is about a quarter of a turn with the paper towel and the bead release breaks and the bead is ready to spin and come off the mandrel. Eureka!
Nicer towels like Bounty last a long time, but even crappy napkins can be used in a pinch. But they disintegrate quickly.
Sending best wishes for a wonderful 2017!
