You'll need a Xikar or a Palio, and a Cuban Crafter Perfect Cutter.
Go to your B&M and see about using both the Palio and the Xikar. Both are excellent cutters with very different designs and feel. Figure out which you get a better, more comfortable cut with and go with that. Both have great blades and lifetime warranties. One thing the Xikar has over the Palio is solid construction. The Palio is made with plastic and can have a little give to it. The Xikar is solid and feels sturdier to me.
The Cuban Crafter Perfect Cutter is another cutter with a lifetime guarantee and it works great. It's cheap and can be your everyday carry, or one you keep in your herf-a-dor or car, or to events where you could lose it. Reliable but cheap.
