Out of desperation I have used the small knife I keep in the car to cut into the cap in an X pattern and I have not been disapointed with the results, but I am not a "purist" freak.
Also used a big folder my buddy had on him to cut the binder and wrapper off a torp once and it smoked pretty well too.
I use a V on everything but torps, for me at least less chance to have cap unroll, flake etc.
