For those critters that just don't care what bait you are using.
The SFFG (pronounced Suff'ff-Gah... just kidding) The Survival Gig is made from fully heat treated and tempered stainless Bohler N661 steel. It is tough, stainless, weighs about 1.5 oz and is sized to fit in a pocket, 4" OAL, so it'll be ready to use when you need it. This is the standard sized Survival Gig.
We also have a limited test run of 5" survival gigs designed for my friends who live along the coast. The longer tines are intended for more meaty prey than bullfrogs and carp. I'm hoping they are sufficient to take flat fish and stingrays of appropriate size.
I've only made a dozen of the longer gig this batch so act quickly if you want one.
Hafting the Gig is super simple and takes only a minute or two with just a length of paracord. Or it can be attached with screws through the 4 eyelets. Ether way it quick and easy to secure the Gig to a suitable limb or pole.
It is somewhat patterned after an Inuit Leister Spear. The oversized barbs and central tine work by capturing and holding a large chunk of meat. Though the gig is intended for frogs and small fish it will hold onto surprisingly large quarry. I tested a prototype successfully on some carp last spring.
From frogs to fish this little Survival Gig will do the job while taking up almost no space or weight in your kit. Aside from a survival situation, please check your local game laws before using.
