Bobby pins will work better than anything else. They have rubber ends that don’t damage ano, and you can easily loop them through your knots for quick and efficient untying.
I use a string buddy clipped to my bag. It’s a spring loaded knot pick on a retractable cable thing. Is it over-engineered for a knot pick? Absolutely. But is it cool? Extremely.
They were giving these out at worlds if you let them film you doing a trick tutorial. I feel like this is something I wouldn’t have purchased on my own, but now that I have one I use it constantly.
Metal wire paperclip. You can find it practically everywhere, you can carry it in your pocket, in your wallet, etc.
I got my O-ring Pick Tool in the mail last week, I use it all the time now! Great suggestion @SlowThrow. Perfect timing too, a lot of the tricks I’m working on right now are knotty tricks.
Awesome!! May your string remain knot free!
