Sorry about your accident but now you have learned the hard way why the concept of skeletonized handles doesn't work well in practice. Any stick/rattail tang knife with a solid grip is going to be far more durable. On a skeletonized handle the frame is going to be heavily stressed and likely to break where it meets the blade, especially if there are any sharp corners. More so if the steel is low quality and the heat treatment wasn't perfect.

I could never understand why people like skeletonized neck knives aside from the "cool & tactical" factor. They're a pain to use because even with a paracord wrap the grip is basically too narrow and digs into the palm too much. I certainly wouldn't carry one as a serious backup blade. If that's all you end up with in an emergency you'll be in trouble - I think you'd be better off with a SAK.

In any case, a small Mora makes an infinitely better neck knife. The size/bulk difference is negligible considering you get a much stronger knife with an excellent blade that can actually stand up to heavy duty work. But again, YMMV!
