Simple is often best.
The Bullet Punch Cutter is a straightforward as it gets. It's a two-part punch cutter attached to a key ring that snaps apart to expose a sharp cylindrical blade. A light twist easily removed a clean hole in the head of your cigar, and when you put the pieces back together, it will eject to plug so it's clean and ready to use again. Its compact and convenient design means that you're always ready for your next cigar.
