@Ibot39 Mostly sandpaper because you nicked it with the Dremel?
You are not alone in your madness. I found my pick over 10 years ago, V-Pick Dimension Jr or Diamond 4.2 mm. But they are expensive and wear out so I file them. See pic. I find it very relaxing. Bought a mini vice as was destroying my fingers.
If you want to part with the thick Gravities let me know. The 2 in the top right corner look cool.
