Designed to be a natural extension of the hand, the Thumper keychain ring is the perfect lightweight non-edged pocket defense tool. With a Brass or Titanium construction, the Thumper is as deceptive and devastating as it is attractive. This tool is small enough to hang from your keys or a necklace but still provides the ability to punch through dense objects. 

Every Thumper is made by our talented manufacturing team here in San Diego, California, and is ideal for everyday carry.
