Sling

The sling was used for warfare and for hunting from antiquity, up to very modern times (my father was taught to use one as a boy).  

Famously used by David against Goliath, the Romans and all of medieval Europe.

This medieval sling is based on a fairly normal construction type of a veg tan leather pocket with slits allowing it to be moulded slightly and comes with waxed cords and a finger loop.  The cords are 36″/90cm long.
