Silly me, I forgot to add...

I regularly use my XiKar cutters (I have two) and they work wonderfully. I very much like XiKar's warranty and how well built their cutters are.

I also have a Palio cutter which was recommended to me by Craig. It does an excellent job on all types of cigars, is very sharp and easy to use, and is not overly expensive.

I keep a cheap cutter stashed in each vehicle, just in case, but those have never seen any use. If I'm out somewhere and don't have one of my regular cutters with me, I generally find out when I go to cut the cigar. In that situation it's faster/easier too grab the Swiss Army Knife out of my pocket than it is to run back to the car/truck to get the one stashed in it.
