Rugged, aluminum-encased Whisker Biscuits are 300% stronger than previous models.  And, added a rock-solid, dual-bolt mount and a set screw for even more secure, "locked-down" mounting.  The Whisker Biscuit's design makes setup easier than ever before.  Attach the Whisker Biscuit¨ to your riser mounting holes and it automatically lines up the arrow rest.  And most models are designed for use with left and right hand bows.
