Count me in. Is their a way you could just dip the handle section in res-c? Sure it wouldnt last forever but if you had one that you stashed in a tin, it would be coated and ready to go if needed.
Don't think res-c works like that, but get a can of plastidip and you're good to go <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Personally I like paracord wrap.
Maybe make the handle like two prongs with a V cutout in between with some points on the inside of the shape like a fishing/eel/frog gig?
Obviously it would only work for spearing stuff or catching very small things, but it would make it easy to secure it as a regular spear point without much possible movement unlike the knife in that video.
Add a hole between the gig cutout and the blade for a lashing point.
