Abstract: An improved cutting member for a rotary trimmer. The cutting member is formed of a flat link chain, so the cutting member is flexible throughout its length. Alternate links are somewhat wider, and may be sharpened on their edges for better cutting. A hardened wear member is at the ends of the cutting member both to receive the hard wear of cutting against hard surfaces and to provide a more massive end to assist in holding the cutting member out during operation.

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.
