Designed by 6-time World Champion Mark Drury and approved by the DOD Team, the new Tongue Series mouth calls are designed with cutting edge technology. Mark has found that by tightening up the reed spacing and leaving a flat tongue instead of a pointed tongue he gets more performance out of this new series of mouth calls as will you. The Tongue Cutter Plus is a typical Cutter call cut Mark designed back in the 80's with his signature notch & .5 Inverted V.
