I don't know if it's HC / PC, but I've made a few knives on a custom basis (for the children: all children should be well armed) where the handle is carved to fit their particular hands ... kind of cool to have them get glop on their hands and grab the scale, then whittle some and then have them re- glop their hands, then repeat until they catch on that they're having to glop and grab a bit more than might count as a bad joke ...
just for your consideration ...
