Xikar 007,008 or 009 Cutter Opinions

[Throb]

I've been punching my cigars lately and have been enjoying the cut. I have a very cheap cutter that has rusted and become dull.

Looking for opinions of the Xikar punches. I like the 007 and 009 as they seem to be one piece units and losing the cap or cover would be impossible. I heard that one of these models also sharpens the cutter every time its extracted to retracted.

THanks for the info
