Basically to test the strength of antlers (for slingshot frames), I made a test dagger today, took me about 30 minutes to make.
I cut off a halfway straight part, sawed the tip off, glued in a threaded 8mm steel rod and sharpened the whole thing. I filed in a rudimentary handle.
This came out way better than I thought! A mean, crude, but no doubts dangerous home made weapon.
Not a slingshot
