A cigar cutter is a mechanical device designed to cut one end off a cigar so that it may be properly smoked. Although some cigars are cut on both ends, or twirled at both ends, the vast majority come with one straight cut end and one end in a "cap" which must be cut off for the cigar to be smoked. Most quality handmade cigars, regardless of shape, will have a cap which is one or more small pieces of a wrapper pasted onto one end of the cigar with either a natural tobacco paste or with a mixture of flour and water. The cap end of a cigar is the rounded end without the tobacco exposed, and this is the end one should always cut.
There are three basic types :
Guillotine (straight cut)
V-cut (a.k.a. notch cut, cat's eye, wedge cut, English cut)
