Unreasonably Sharp Jaws for Bear Trap

I archived these scary-looking jaws from [Bear Trap - Improved Version](https://www.thingiverse.com/thing:6452107) in Feb 2024, before rowiac replaced them with `Jaw[12]_Less_Sharp.stl`.

I also added `Jaw[12]_Even_Sharper.stl` which sharpen the jaws to the limit of your slicer.

Print at your own risk, lol.
