The cigar cutter is a hand tool that is used to cut the tip of a cigar before lighting it. It can be small scissors (about 6-10 cm) with two crescent-shaped blades or one of which has a round cutout and the other a concave cut.
Another model has a blade with a round cutout - where the tip of the cigar fits - and a straight cutting blade that can be moved along the cutout using the lever principle. There is also the option of making a V-shaped cutout at the mouth end of the cigar.
Sometimes this last model is combined with a cigar box opener or it is part of a pocket knife. [MOT]
