Combat Training Knife (With Handles)

I printed the knife blade in TPU 95A and created the handles using Red Lipstick PLA. The handles are secured with M3 x 8 mm bolts and press-fit M3 hex nuts. This setup makes the knife durable enough for realistic training, and I now use it with my Krav Maga students to safely practice knife defense drills.

PROTIP!

When printing TPU, I use OrcaSlicer. Even with my Prusa MK3.9S, I simply load the MK4 profile and select Generic TPU (since I’m running Elegoo filament). It works perfectly — no issues, no tweaking. I literally just set it and forget it.
