Evel Knievel's Bike Helmet

Origins
Evel Knievel was a stuntman who would do jumps on his motorcycle from one ramp to another, usually with something deadly or hard in place of a safety net. He tried, and failed, to jump across Snake River Canyon in his steam-powered rocket, the Skycycle X-2. He suffered over 400 bone fractures during his career, earning the Guinness World Record of most bones broken in a lifetime.

Effects
The first (and one of few) helmets that Mr. Knievel ever wore; the thrill of his excitement on the bike was quickly absorbed by the helmet, which recognized his potential talent on bicycles. Wearing the helmet gives the user physical prowess and hyperawareness, but breaks according bones in the user depending on what the helmet is used to do.
