Reprofiling tipped Main

My wife picked up a Kutmaster stockman today that that had a badly tipped main blade.
I thought I would take pictures of how I reprofile a broken blade:
1. I find and mark the center of the break.

- Center if break marked
2. I draw out an outline of where I expect to grind.

- Lines marked
3. I grind the backside of the blade first, almost down to my line. I use a 120 grit belt on a 1x30 belt sander, keeping the blade cool by dipping it into water.
4. Then I grind the front of the blade.
5. I thin the sides of the blade just a little to restore the distal taper (not shown), then switch to a 400-grit belt and refine everything.

Great work there. Being skilled at doing that sort of work is a skill in itself.

Looks great. So many I see the people try to just grind the top and bring it to a point never changing the sharpend side. That always makes a strange looking point or off center one to me, and the way you did it spine and sharp both works perfectly.

Great job! Breathers new life in to an old workhorse.
I’ve always been a sucker for old Delrin Kutmaster knives. They had great steel in them. Fantastic old users.

That’s a really helpful explanation of how you do this. I haven’t tried that on one so badly broken just a few with the tip missing. Now I know how to do it. Thanks. Looks fantastic.

The 2nd picture threw me for a loop for a moment! It was the picture I noticed first and the junk in the nail nick made it look like it had been cut out, same color as the background.
Your finished product looks great, a great way to salvage an old war horse!

The way you did it makes a lot of sense. Great job and
excellent method showing us in pictures. Almost wants
myself to go and find a broken knife and see if I can
do it.

Nice save and tutorial! The only thing missing is a nice swedge on that blade!
