Been smoking cigars for 50 years. Moved to hand rolled, long fillers in the early 80s and now if I can't smoke a good stick I don't smoke. (Same with drinking bourbon, BTW!)
You need to understand that a good stick is a piece of craftsmanship. To get a good cap cut and fitted to a cigar correctly, it is estimated that it takes about three years to completely master the cap. Since a good roller can roll and cap about 125 cigars a day, think how much effort it takes to master the cap! That is why so many have bunchers, rollers, selectors of wrapper, then rollers. After rolling the stick to to a specialist, or to a roller with the experience to put on a cap. I am disgusted by those that hack then end off a stick with one of those guillotine monstrosities. And scissors wear out quickly, especially if you buy cheaper cigars on occasion as the stems on some can be quite thick and they dull the scissors and split the blades apart. You wind up tearing the end off your cigar with those things in pretty short order.
Somewhere in the late 70s to early 80s I read premium cigars were opened up to smoke with a "V" cut, slicing through the cap and making a cut that held in profile looks like PacMan. It serves a couple of purposes to do that. First, in heavy duty cigars tars and nicotine deposits can build on the end of the cigar; with a "V" cut it sits in the cut and doesn't get on your tongue. Second, the cap is engineered to stay in place and to keep the end of the cigar from unrolling. And for me, a little tip of the cap to the artisan that rolled the stick.
I always kept a small, very thin, slicey bladed knife in my pocket for my cigars and cut them myself. Did that for decades. Now there are a few brands that cut a perfect "V" for you. I bought a Colibri brand many years ago and it has cut a ton of smokes and shows no signs of slowing down. It has an over sized aperture which is good for me ( I like 52 - 64 ring gauge) and the blades stay amazingly sharp. Only on occasion do I cut my V with a pocket knife, but I have a Barlow with the secondary blade's edge laid waaaay back so it does it just fine.
Enjoy the smoke!
