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 on to 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. The cap may be cut with a knife or bitten off, but if the cap is cut jaggedly or without care, the end of the cigar will not burn evenly and smokeable tobacco will be lost.
There are three basic types of cigar cutters:
The straight cut is the most common, usually used on cigars with a smaller ring gauge. This cut uses a quick straight cut causing both ends of the cigar to be exposed. The double blade guillotine is preferred by many aficionados over the single blade, because it usually makes a cleaner cut. Cigar scissors are also used to make straight cuts, and may be the best choice for cutting the cigar with exactness. However, the guillotines are usually the most practical, the least expensive, and can be easily and safely carried in shirt or trouser pockets. Most prefer this cut because the entire cap end is exposed allowing for maximum smoke to exit with only minimum buildup occurring around the edge.
