A hand-held hemming mechanism consisting of a operating and stapling mechanism. The stapling mechanism consists of a hammer assembly, operated by a bar connected to a handle. The staples are held in place by the body, a pair of staple hold down assemblies, and the pusher plate. The staples are advanced by a compression spring mounted behind the pusher plate and contained in the rear of the body. A range of staple heights can be accommodated by this construction. A cover with measuring marks covers this upper portion of the invention. This cover also determines the amount of opening allowed for adding or replacing staples. The crimping is provided by an anvil mounted on a lower bar. This anvil has two different crimping slots for the range of staples used. There are two support bars than can be used with this device. One is configured for thin to medium thickness material that has a short hem. A second support bar is "u" shaped to provide a material accumulation for hems that are far longer. This "u" shaped bar is also used for thick material, no matter where the hem is. The support bar in use is mounted on pins that are permanently attached to a support bar actuator, which has a handle mounted to it. The anvil is machined in such a way so it is capable of being used with all staple heights and both support bars. The operating mechanism is power by using a scissor like hand motion which rotates both the upper and lower bars around a pivot pin thus forcing the staple into the material and crimping in the anvil. A wide variety of staples of different materials and colors can be used.
