  1. How about sanding stone?

  2. Is there any real reason for the 30 degree edge? I would assume that if you go closer to 20, the grass would cut even nicer but the blade will dull faster.

  3. Here's a new video idea: test a couple of induction heaters which are often needed to remove the blade from the lawn mower if there's lots of rust. Are there any meaningful differences between induction heaters (many products are pretty expensive but the idea is to just output suitable magnetic field so I would guess the cheaper models are just fine as long as they don't totally fail)?
