Abstract

A manual dental and medical living tissue cutting instrument for obtaining living tissue grafts. The manual dental and medical tissue cutting instrument includes an elongated member with two portions. One portion is sized and shaped to be grasped by the hand of the user of the cutting instrument and the other adjacent blade holding portion that is located at the end of the elongated member and is adapted to hold two removable blades. The blade holding portion is adapted to hold the two removable blades in an angular relationship with each other in such a manner that the pointed ends of the removable blades either touch or come in close proximity to each other. The invention includes both the elongated member with its handle portion and blade holding portion without the removable blades and the combination of the elongated member and the removable blades.
