The only way to get better at something is to start doing it, and keeping at it. It's very possible that a kid will decide that using tools is not his/her thing, but you never know if you don't let them try. It's the same with letting a child, cook, or paint, or a million other things. If you have the confidence to let them fail, they'll have the confidence to keep at it.
