Whisker Biscuit kept all the features that made it the most popular arrow rest in the world and made the changes bowhunters asked for. They made it tougher, lighter and more compact. The composite-encased Kill Shot Biscuit is 150% stronger than previous models. Use the laser-engraved marks to fine-tune the windage adjustments. You can also make elevation adjustments for even more fine-tuned shooting accuracy.
