Abstract: The painter's tape dispenser with cutter has a base, a rotatable spindle for receiving a roll of tape, and a cutter mounted on the base, which is ergonomically dimensioned for a comfortable fit on the user's forearm. The base is generally triangular in shape, with a pair of elongated sides and a relatively narrow base of the triangle, so that the base is adapted to extend along the inside of the forearm between the elbow and the wrist. The spindle is mounted on the wide end of the base and the cutter is mounted opposite the base, which is retained on the forearm by a pair of straps. The tape dispenser is positioned ready for hands-free tape dispensing when the spindle is loaded with a roll of tape.
