Saw a podcast where they said editing is harder than writing, totally agree lol.

Started with a bamboo fun back in 2010 and still use it for quick sketches sometimes.

Man, that's the worst. I keep a basic backup saw, just a cheap manual one, for exactly this reason. It's slow but it'll get you through the day. After my grinder died mid-smoke, I also started a small "tool fund" where I put aside fifty bucks from every big job for eventual replacements.
