strips or tubes attached to the upper two ends. The other ends of the strips lead back to a pocket that holds the projectile. One hand holds the frame, while the other hand grasps the pocket and draws it back to the desired extent to provide power for the projectile—up to a full span of the arm with sufficiently long bands.

For much of their early history, slingshots were a "do-it-yourself" item, typically made from a forked branch to form the "Y" shaped handle, with rubber strips sliced from items such as inner tubes or other sources of good vulcanized rubber, and firing suitably sized stones. While early slingshots were most associated with young vandals, they could be effective hunting arms in the hands of a skilled user. Firing projectiles, such as lead musket balls,

s, air gun pellets, or small nails, a slingshot was capable of taking game such as quail, pheasant, rabbit, dove, and squirrel. Placing multiple balls in the pouch produces a shotgun effect (even though not very accurate), such as firing a dozen BBs at a time for hunting small birds. With the addition of a suitable rest, the slingshot can also be used to shoot arrows, allowing the hunting of medium-sized game at short ranges. While commercially made slingshots date from at latest 1918, with the introduction of the Zip-Zip, a cast iron model, it was not until the post–

The early production of the Wrist-Rocket slingshot was a joint effort between Saunders Archery Co., who came up with the trademark and developed the automated forming machinery, and Mark Ellenburg who came up with the basic design. A few years later Mark Ellenburg split away forming his own company called Tru-mark Manufacturing Company. Today Saunders Archery is still a major innovator in the slingshot industry with its line of flatband slingshots which use locking clips for band attachment and  tuning.

Dangers

One of the dangers inherent in slingshots is the high probability that the bands will fail. Most bands are made from
latex Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms ...
, which degrades with time and use, causing the bands to eventually fail under load. Failures at the pouch end are safest, as they result in the band rebounding away from the user. Failures at the fork end, however, send the band back towards the shooter's face, which can cause eye and facial injuries. One method to minimize the chance of a fork end failure is to utilize a tapered band, thinner at the pouch end, and thicker and stronger at the fork end. Designs that use loose parts at the fork are the most dangerous, as they can result in those parts being propelled back towards the shooter's face, such as the ball attachment used in the recalled Daisy "Natural" line of slingshots (see image). The band could slip out of the slot in which it rested, and the hard ball in the tube resulted in cases of blindness and broken teeth. Daisy models using plain tubular bands were not covered in the recall, because the elastic tubing does not cause severe injuries upon failure. Another big danger is the fork breakage; some commercial slingshots made from cheap zinc alloy may break and severely injure shooters' eyes and face.

Legal issues

Many jurisdictions prohibit the use of arm-braced slingshots. For example, New York Penal law 265.01 defines it as a Class-4 misdemeanor.
