Abstract: A collapsible cigar corer tool assembly is disclosed having a body and a collapsible cigar corer including at least one cutting aperture with a fixed, circumferential, cutting blade. The cap of a cigar is prepared for coring an opening by urging the cap against the cutting blade and by rotating the cigar relative to the aperture. The cigar corer is mounted on the tool assembly such that it pivots between two positions, a first closed position in which the cutting aperture is housed within the body, and a second open position in which the cutting aperture is in an operative position outside the body.
