Remove the biscuit from the windage bar. Lay the tips of your sissors flat against the bowstring side of the biscuit. Lift and snip about 4-5 bristles at a time working evenly around the circumfrence of the biscuit and taking care to remove the upper layers of bristles first in an even fashion. When you can look at the biscuit edgeways and its flat with no bristles sticking above it STOP. Good luck hunting!
