This fishing spearhead uses elm cordage to keep the two prongs from splaying apart. Using pitch, I have attached sharp chicken bone slivers to the angled ends to provide both a sharp stabbing end and a barb.
This design utilizes the natural split in branch or twig.
However, in the video I am using a buckthorn (Rhamnus cathartica) "V" or "Y" piece of twig. Pine pitch () as natural glue, turkey bone for barbs, and dogbane cordage for cabling. This is a fairly large piece that could be used for very large quarry like carp, sheephead, or northern pike. Obviously, one would scale this tool down to be relevant to the species of fish one is after.
