Abstract: A hollow cutter body having an opening is adapted to slidably receive an end of a cigarette lighter. The opening is defined by a cutter body wall that has a slot extending from an end of the cutter body opposite to the opening, and at least partway along a length defined by the cutter body. An aperture is also defined by the cutter body opposite and approximately aligned with the slot and includes a sharpened peripheral edge, against which a cigarette can be trimmed. The cigarette is trimmed by sliding an end through the aperture and the slot and actuating the cutter body by moving it along the lighter, causing an end of the cigarette to be cut.
