Tested extensively by qkrehf2 on the community discord.

Unlike v0.2.2a in v0.2.2b sandpaper has no effect, even when being applied correctly (sandpaper in offhand, tool in active hotbar slot, and holding r-click as if to eat).

Sandpaper polishing on tools has been removed intentionally. The side-effects of it were frequently seen as bugs and generally counter-intuitive.
