Hello What are they? B and T
Yeah, bushcrafters and woods people like them because they don't need a drill or any power, you just need a stick to push through the hole to act as a handle. Nice for green woodworking if you like doing things the old fashioned way by hand.
Are they in decent nick or have they been abused?
They are a bit rusty but not eaten away and should clean up nicely with a wire wheel and a bit of oil. Cutting edges look quite decent and should be OK with a bit of a touch up with a fine file or something.
