Punch cutter question

[CigarSquid]

I like them. I used them all the time when I first got into smoking. I too, have one on my keyring. I still use it, just every time, but I would say 1 in 5. I do notice the build up but nothing crazy.

I have used the punch cutter on the Diesel Shorty, CAO Gol and Ciao(big ring gauge) Normally I use one punch.. If I feel it is to small.. I go ahead and punch another one.. Giving the outline of a 8.
