The Winkler Emergency Response Tool (ERT) is made from solid carbon steel with a Caswell treatment to give it a no glare finish, and to help impede rusting. This hefty 9-inch breaching tool blends a hammer, glass breaker, wrench set, and heavy-duty pry bar into a no-nonsense build. The ERT is a smart addition to any toolbox, gear bag, or emergency car kit.
