I have an old, rusty, small German saw with a ridiculously bad plastic handle. I've been playing with the idea of cleaning it up, putting fine teeth on it, and making a child's sized handle out of wood.

Has anyone simply shrunk the pattern for a normal handle to use by a child? If not, does that sound like it should work?

Or does anyone have experience with "real" tools for children? I'm hoping to make it easier for my 5-year old to get started with a saw.
