I remixed the BearClaw Knife by Lord- @user_127415336.
It's remixed to have an actual double-sided blade, not just one side and the other completely flat. I also added a little tang length to fit better in the palm. Use the print profile provided and it should be very strong, make it 100% infill if you want it even stronger.
The file has 2 variations, one has a slightly thicker “Handle”
Working on a tpu Cap for the tip of the blade so its pocket friendly.
