I've been smoking for a couple years now and to this point have just used the free cutters that came with starter kits and such. I'm thinking I want to invest in a good quality cutter that I will have for a long time. From all accounts a Xikar is what I'm looking for. Is there any significant difference between the Xi1, Xi2 and Xi3 cutters? So far as I can tell it's just a design thing but if anyone has any insight that'd be appreciated.

Anyone have any negative experience with Xikars or have any other suggestions for a cutter? I'm all for the consensus but I like to explore my options. Reccomendations for non-Xikar cutters would be appreciated too.
