The Reverse Hammer is a 3 reed diaphragm call. One top red reed over two proph reeds. Designed with WoodHavens Hammer Cut. The cut is on the left side of the call instead of the right which allows you to manipulate where the air is flowing through the call. Creating more unique sounds. This call will produce raspy yelps of old hens, as well as high pitched runs of a lost turkey, too hard crisp cutting, yelping, whistling, and soft clucks, purrs, and whines. The Red Reverse Hammer does it all.
