Adam, lady and gents-
Just to throw my 2 cents in...
I have used: 1 blade, 2 blade(Xikars and generics), v-cuts, punches, cigar scissors, regular scissors, teeth, knives, and anything else sharp that was handy when I was trying to "cut" my cigars (I even used the mouth of an open can of beer once)...but IMHO the best cutter I have used is the SAK. I have been using it for only about 3 months, but it cuts tobacco like butter. The only ragged cut I have had so far was when I sneezed during the cutting operation.
