Are you easily mesmerized by reruns of World's Scariest Police Chases or compelled to click on YouTube pursuit videos? One such all-night binge session, ending with a video of a serious T-bone crash with a civilian, left Leonard Stock unable to sleep. Restless, he germinated the idea for a tool to help law enforcement officers end such chases more safely.

His idea was a vehicular lasso to grab a perp's vehicle by the tire. A roofing contractor by trade, Stock was naturally handy and a proficient welder, so he began prototyping the concept on his own vehicle. He quickly confirmed his theory that a moving vehicle's spinning tire would indeed pull a loop of tow-strap material around itself if said strap could be forced into firm contact with it.

That prototype led to many iterations, all of them self-financed by Stock and his lucrative house-flipping business in the booming Phoenix metro area. His final Grappler design uses 2-inch nylon webbing with a 20,000-pound test strength; in many instances it's doubled for a 40,000-pound capacity.
