Abstract: A holder is described which holds a conventional, single-edge razor blade and permits the blade to be held safely in the hand and used to cut thin, elongated articles, such as sheets or strands by drawing the blade into edgewise contact with the sheet or strand. The cutting edge of the blade is protected except for a portion thereof, which is exposed at the end of a guide slot in the holder, which serves both to guide the article being cut into cutting contact with the blade at an optimum angle of incidence with respect to the blade, and to prevent other articles and parts of the hand from being cut accidently. The blade is replaceable without tools and is reversible to use portions of both ends. A finger extends outward from the holder and parallel to the guide slot to hook the article to be cut into initial engagement into the guide slot.
