A handy rotary cutter comprises a generally elongated plate-like handle (10) having a bearing aperture defined at one end thereof, a shaft member (18b) supported by the handle (10) and extending through the bearing aperture, a disc blade (13) rotatably mounted on the shaft (18b) and lying in a plane perpendicular to the longitudinal axis of the shaft member (18b) and in parallel to any one of the opposed surfaces (10A, 10b), of the handle (10), and means (19) for adjustably applying a frictional force to the disc blade (13) in a direction generally perpendicular to the disc blade (13). The disc blade (13) is, when the rotary cutter is in use, rotated in contact with the material to be cut in a controlled manner. |
