Designed by the Bone Collector's Michael Waddell, the Razor's Edge is the most ground-breaking box call on the market. For the first time ever, this call utilizes an aluminum striking surface onto a traditional box design. The aluminum edge creates in a uniquely raspy yelp while the wood edge creates the smooth tones of a traditional box giving you two calls in one. The Razor's Edge utilizes Knight and Hale's patented Switchblade Technology so that the lid can be quickly removed for silent movement through the woods without rubber bands or Velcro. The lid is also interchangeable with all lids from the Knight and Hale's Switchblade box call. All Knight and Hale box calls are proudly made in the U.S.A.
