I have a Cohiba Xikar and a Prometheous that I got from a lighter set...but lately Ive been using a cheap "V" cutter. If anyone knows of a nice $25-$40 "v" cutter let me know!
Currently using a generic double guillotine. I had a SAK but it got donated to the Vatican Guard while I was in Rome over Christmas which I was rather pissed about. So right now I have a Palio on the way. I will get a SAK again I loved that thing it cuts so well!
Xikar with wood handles. love it have had some issues if the cigar isnt firm enough but thats the cigar not the cutter. i love it would like to try a Palio they seam like you would get some good cutting force.
I use a cheapo "Craftsman's Bench" double-bladed cutter for my torpedos, but mostly I use a punch - built into the bottom of my torch lighter. Some Chinese special, but it works very well.
