No, not angle grinders. *Bench* grinders. Cheap. Aldi are selling them, GBP11.99 for a 200W grinder, comes with one fine and one coarse wheel. Seems like a bargain to me, and should be good enough for my purposes. They're also flogging pairs of extra wheels for GBP2.99. Now, what needs sharpening? All my knives, scissors, the mower blade, axe... ummm... pizza cutter... damn, there must be other stuff...
