Welcome aboard the ship.
V Cutters. I second bstessl. It is preference for you. Some like the V cut, some a punch, some a guillotine. V cuts are tougher on torpedoes, belicosos, and pyramids and punching is almost impossible on these as well. I have a V cutter for larger ring gauges 52 or higher just because it helps to regulate the amount of smoke I get.
Hope you enjoy your time here. Get involved in trading, buying, selling, passes, the boards and the live herf. There is a ton of information here from the cigars themselves (sizes, shapes, flavors, profiles) to storage, and all the way up to a huge cigar database with tons of reviews. You just can't go wrong.
