As the title says, I'm looking to turn my SS into a spearhead. I don't want to make it sloppy or just bind it to the side of the shaft or anything like that, so here's what I was thinking. After acquiring a straight, good, haft, I would use a saw slightly thinner than the handle of the SS with no scales, and cut down the haft, perpendicularly till I could snugly push the knife into it right up to the guard. Perhaps round out the back of the cut to accommodate the curve of the ring. Tap small started holes where the screws that hold the scales on are, and put some high strength nuts, bolts, whatever, through the haft at these points. Basically what I'm ending up with is a similar concept to how the Trench Hawk goes together. My questions....... Can anyone see a way of improvement on any of these concepts? I'm worried about the lateral stress on the points of connection, and fear the haft would split easily. Perhaps a hard epoxy on either side of the handle and a tight 550 cord wrap, but this would make it difficult to quickly remove the blade to convert it back to a knife. Ideas? Thanks all!
 
That's a very plausible idea I hadn't considered! Another thing I was pondering would be alternative materials to wood for the haft. Some sort of light hard plastic or even a composite like many of the modded Trail Hawks have. It would be a shorted haft for sure. Anyone know of appropriate alternate materials?
 
Delrin (POM) is pretty strong, but I don't know how suitable it would be at the length and diameter of a spear haft. You can get lengths of it online in various diameters (usually priced by the foot). A site called Plastics International sells a 1.125"x5' piece of black delrin rod for about $30 (less shipping). Not cheap, but about the perfect size for your purposes. It would be an experiment, of course. Like I said, it's very strong, but I've only seen it used in smaller parts. Wish I could give you a better answer, but that's all I've got off the top of my head.
 
Langettes would add a lot of strength, or in the same sense you could bind the entire joint plus a few extra inches of shaft with paracord, as tight as you can. If you are going to add screws/bolts I would make them go all the way through, not tapped into the handle. Stronger, I think. Remember, pics or it didn't happen! :thumbup:
