For those who remember, this call is the “Magic Mooncutter” reborn — For those that don't, this is a call that can do it all. Designed by Harold Knight, the Half Moon Cutter allows a hunter to make any sound a hen could make but really shines with its high-pitched yelps and aggressive cuts. The versatility and hand-free nature of this call allows you to get up-close and personal with those tricky toms.
