Regarding knife throwing and self defense:
In the mid 90s I was very much into all forms of self defense, including edged weapons. Overall, I've had about 75 hours of formal edged weapons training from expert instructors. In each class I took, there was inevitably one guy who would ask about throwing a knife as self defense. Universally, the instructors shot down this premise on a number of fundamental truths:
- Fighting with a knife is exclusively about blood loss. Rarely does one single stab result in the blood loss needed to immediately incapacitate an attacker. And the average folder isn't long enough to reach most vital organs by the average user, which means that multiple strikes will be needed to cause significant blood loss.
- The average thrown knife will likely penetrate only 1-2 inches. It will not reach vital organs, assuming you make contact at all. Speaking of:
- Most knife throwers can't reliable hit a small target under perfect circumstances. Under pressure, with a moving target, you'll probably miss entirely. Once that happens:
- If you're fighting with a knife, it typically means you've either exhausted your other weapons, or it's the only weapon you had to begin with. Once you've thrown it, and likely missed, you have nothing.
- Finally, folders lack the balance and aerodynamics to be thrown consistently.
