For master marksmanship, nothing makes every throw count like the Devastator 95% Tungsten Black Steel Coarse Knurl Steel Tip Darts. Designed with Hammer Head tip to guarantee no bounce-outs, each dart is crafted with a super tough Tungsten barrel and a durable nylon shaft. The coarse knurl grip provides complete comfort, while the choice of weights allows you to customize your purchase to your preference levels. The patented Hammer Head mechanism uses a unique point, clip, and barrel design that allows the tip to retract into the dart slightly on contact. The point slips off the obstructing wire, and then the forward thrust of the dart hammers the point into the target. And, with that, you"ve virtually eliminated bounce-outs from your game. New O-ring technology to keep all points securely locked. About Bottelsen Bottelsen Dart Company is an American manufacturer of championship steel- and soft-tip darts.
