'TRAK' is an acronym for the 'Titanium Runner’s Anywhere Knife' -- a product that was created in order to increase running safety. As many athletes hit the trail alone, TRAK brings an extra measure to ensure that runners are able to defend themselves in the event of an attack.
The knives can be used for defense by "anyone, anywhere" and were originally designed as a backup tool for fishermen and divers who were entwined in fishing lines.
The titanium knives were built for running safety in that their design boasts an ultra lightweight feel and is almost impossible to drop. The TRAK can be worn virtually anywhere and each comes with a sheath to keep the blade hidden, making it work as a necklace and key chain that can be attached to an arm band.
