Just teach them how to do things safely whilst you watch them, otherwise they'll only go and do them behind your back without any guidance I was allowed to use any tool when I was growing up
I've only ever seen one broken Record 36 and it was still usable despite the hole in it. They are a nice vice, they have more clearance around the slide than more traditional looking vices.
I do like that... and have the exact same vice too Also have a couple of other funky jawed vices, although sadly not a fractal jaw one as they sell for literally thousands now.
