Ah, the crowbar. Long heralded as the premier weapon in the defense against zombies due to its long reach, skull-spearing ability, and no need for ammo. This titanium model is sure to deliver. The Manta Titanium Crowbar ($110) was originally developed for scuba rescue divers who needed something lightweight that could open anything. Weighing in at less than 2 lbs and with a reach of 22″, the Manta crowbar is one that even Gordon Freeman would wield.
