Abstract: A multifunction cutting tool includes a cutting head adjustable for straight, free form or circular cutting of glass and tile, interchangeably mountable hobby and hook blades for cutting carpet, PVC, matting and the like, a roller cutter for cutting cloth, wallpaper, leather and similar sheet material, knife and scissor sharpeners and an angled carpet cutter blade mounted in a carriage with a base plate for sliding under the carpet. The tool has blade guards to protect the user from accidental injury and brackets supporting the cutting blades that are stabilized by resilient snap fittings and laterally extending support shoulders. Access to retractable folding hobby and hook blades is improved by the addition of screwdriver tip receiving pivot slots in the blades and the work surface of circular cuts is protected by a suction cup having a recessed and covered metal attachment.
