XIKAR'S 7mm twist bullet punch features a unique large bore screw combined with body dimples for grip which allows you to quickly and easily open & close the 7mm blade. The closing action clears tobacco from the punch blade after each use. These solid brass plated punches are available in silver, gunmetal or gold. Use a punch to give a cigar a more restricted draw. The smaller the punch, the more air flow restriction. The punch will neatly cut a small hole in the cap leaving the full shoulder of the cigar intact. To use, line up the punch and cigar. Twist the punch as you slowly push into the cap. Finally, pull straight back and remove the punch.
