Oh man, that burnishing angle is everything! I found if you put a tiny bit of camber on the edge first, it glides over curves without digging in. A little hook is good for flat stuff, but for legs, that gentle curve keeps it smooth.

My friend's baking disaster proves @william_carter right.

Yeah that's a huge problem everywhere. I put up a basic flyer at my local library with a QR code linking to some simple repair guides and common failure signs. Got a few people bringing stuff to the monthly fix-it meetup instead of trashing it. It's not a ton but it feels better than nothing.
