Slungshot - A general term used to describe a weight on the end of a flexible handle. Very broad term. No one really knows the origins of these weapons, possibly from sailors.
Sailors slungshot - a basic model. Made from 9mm jute rope, approx 28" long, the length of the adult arm, weighted with a steel ball bearing. Lots of reach, when swung will get up to a high speed,
delivering a devastating punch.
Sailors Slungshot - leather basket weave over a 10oz lead ball used normally for fishing
Brocc - old English for a badger. Short, flexible bridle leather handle, this one has a bi-colour wrapped lead head. a descrete pocket size slungshot
Cubbie - the junior to the Brocc, smaller weight but longer tail. The loop at the end is designed to take 2-3 fingers only, its not a wrist loop
Pear - I see this as a cross over between a slunshot and shot filled sap, can be swung like a slungshot, but can also be held like one of my Casey shot saps.
