I have read that this is the type you should use if you are serious about hunting and accuracy and self-defense. The guy in the film is amazing, but I would guess that half his proficiency lies in designing, making and maintaining his gear, and only half in shooting. As soon as the rubber begins to wear too much, he’s going to lose accuracy, and probably he has to break in new ones before they’re up to the standard of his old ones. Besides, look how close he is to everything he shoots.

The other kind is much cheaper, and always available in an emergency when there are hard objects within reach and clothes on your back. Imagine the reaction of a mob who pursues a seemingly defenseless barefoot man when suddenly there are 1, 2, 3 of their people down in the dirt with bloody heads, before they’ve even reached him.
