After searching the googles I couldn’t find a whole lot that what give me what I wanted (wooden handle not PVC).
So at your local Home Depot you can find rake or shovel handles for 5.95 and a 1ft section of threaded stainless steel rod for 1 dollar. Assuming you have the an angle grinder, drill, and wood glue or epoxy total cost comes out to less than 10 dollars per gaff.
The shovel handle can pre drilled with a 1/4in hole that I filled with wood glue and then hammered a 3/8 stainless threaded rod just a little more than it should. The threads and glue/epoxy gives a solid bite into the wood. While drying I cut the handle down to 36in and drilled a 1/4in hole through the rod for a 550 cord loop. After drying overnight I put the angle grinder on it to give it a nice chisel point.
