so I broke the tip off of a harpoon fighter is was working on. I had heat treated hit and the tip warped. So I proceeded to clamp it in between two pieces of angle iron with feeler gauges wedged under the tip, pushing it in the opposite direction of the warp/bend. When I was clamping it down with c-clamps I heard a pop. I looked down and the tip had snapped off. :/

So, here are the two options I have come up with to salvage it. One keeps the harpoon and one does not. One question I had was, do I need a shoulder on the spine side of the knife for the guard to butt up against, or could I leave it straight like in the pic of the knife on the right? I can make one, but in order to have enough meat for the harpoon, I’ll have to grind the spine down some.

Here’s what I’m working with:

My opinion FWIT is to try a third option 1) keep the shoulder, 2) keep the harpoon and steepen the clip slightly, 3) curve the belly up more to meet the new clip.
My image of what I'm suggesting involves a minimal amount of change.
 
I think they all three look excellent. Could go crazy and chop the tip for a Wharnie. That would maintain cutting length.
 
Good redesign on the blade.

Just a few comments on the tang.
First - They are backwards if the intent was to hold against pulling free of the epoxy.
Second - The acute angle at the bottom of the "teeth" you ground in make for stress risers. Round bottom notches will hold just as well in epoxy, but be less likely to lead to a break.
 
Thanks Stacey. I’m thinking I might turn this into a take down, so I won’t be putting any epoxy in it. You’re right though. I was working when I was tired and was holding the knife a different way than I usually do when I grind teeth in like that.
