The FS-1 folds down to a compact size. It stores SA30 or SA50 ammo or (matches, small knive, repair kit, etc.) in the handle STORAGE CHAMBER. A valve on the bottom “flips” open to dispense ammo (not included) quickly into shooters hand. (The handle is molded in one piece, and does not contain any glue or rivets.) The WIDE FORK SPACING is designed to increase powerband life. The light, aluminum frame and compact size makes the FS-1 a favorite survival aid for campers, hunters, and backpackers. The wrist-brace can be removed. NOTE: Trumark's FS Series Slingshots are the only FOLDING SLINGSHOTS in the world that include a storage chamber. (The storage chamber also helps the slingshot float if dropped in the water). Includes matched-pull latex powerbands, and large split leather pouch.
