This invention relates to the field of composite bow technology, specifically to a rotary composite bow stop block. The stop block is rotatably mounted and cylindrical. Its surface has an annular groove for constraining the bowstring. When the bowstring collides with the stop block, a cutting action also occurs between the bowstring and the stop block.
