I'm a bit of a knife-nut and have numerous sharpeners including diamond round & tapered types. These are useful for sharpening serrated blades. I've never used one of these sharpeners on a cigar punch cutter, though.
I own several of these, good product -
I don't own this DMT model, but they make very high quality sharpeners (I own many of their other models) -
These can be readily found in outdoors sporting goods stores which cater to hunters, fishermen, campers, hikers etc

Reason: Bought mine locally - Wanted to say these can easily be found all over, not just at the big online store
