Further to the last post and in reply to how the spring barb works. There is a small piece of rubber beneath both barbs that hold them open. You hold them closed with a small stainless ring that is captive on the spear head at the back end of the barbs (floppers). Basically the ring holds the back end of the barbs against the spearshaft compressing the rubber "springs". Even in flight the barbs are held shut but on passing through anything solid like a fish the ring is pushed back off the barbs and they spring open. Hard to explain but a simple foolproof system in practice.
