If you don't think regular slingshots are good enough for say being stranded on a deserted island then you should have a look at the Survival Slingshot.
Designed to be a vital tool for survival, the Survival Slingshot is a formidable compact weapon capable of shooting normal slingshot ammo as well as standard arrows with great accuracy thanks to the wrist support and the Trophy Ridge Whisker Biscuit (arrow rest), which can be set aside for normal slingshot shooting.
Inside the watertight tubular handle is a fishing kit, sewing kit, waterproof matches and striker, and steel slingshot ammo, closed with a tough aluminum end cap with a built-in compass.
