NOT "A". antique tool question

[Tom Wesenberg]

Looks a bit sketchy to me. Safe practice says to use a grinder with tool rests and eye shields. With reasonably priced bench grinders available why chance your personal safety?

Personally I don't want a shield on the wire wheel I use because if I'm cleaning a bolt or nut and it gets away, then the shield traps it and spins it around to spit it back at me. With no shield, the nut just drops to the floor.

Leather gloves is a good idea to save some skin.
