  1. 4:50 - "...and an anvil that prevents the hammer from just pushing a primer around." Theoretically, there's another possibility; if the hammer hits the primer at a high-enough speed, the primer's own inertia can serve as the anvil, removing the requirement for a separate physical anvil. In practice, good luck getting the hammer to move that fast.
