Okay, along with a custom Woodsman resto I am doing ( reference HERE ) I am restoring/modifying and OLD Puma White Hunter.

ONE BIG PROBLEM...in the past, the knife was modified by adding a deer antler for a handle ( YUK ) and in the process the maker ground the tang down severely, to about a thrid of it's normal length.

Here is the knife before I cracked off the antler:



Here is the blade as it stands:



My thought is this:

I am thinking of adding a section of industrial grade  all thread by a combination of pinning and welding ( judiciously ) at the tang and then making a new handle and then threading a pommel to the end of the all thread.  If I am careful enough I should be able to avoid warpage ( beyond any correctable point ) and still end up with a strong, full length tang.

Any thoughts as to the feasability of my idea????

Thanks for any input.

I work with steel construction often and metal warping is always a concern when welding, but it can be minimized with careful workmanship.  I think that your idea will work, but there is the possibility of warping the blade or tang.  If you were not set on making the knife full tang you could construct a new handle out of wood or metal and use the existing holes in the hang.  The knife would be just as durable as it was before with the antler.  If you fabricated a metal handle you could weld that to the knife and it would be all once piece.  Almost anything can be accomplished with enough time and patience.  Keep us updated.

Quoted:
I dealt with these issues when I first started building knives. Eventually I would make a tang to short but the blade was to nice to throw away. I have tried welding extra tangs with Arc and Mig. No matter what, both create alot of heat. Unless you can find a Plasma type welder you are going to transfer heat into the blade. Definately you will wrap the original tang.

I don't know what type of handle you are putting on it but try this, get the metal addition you wish to put on the tang. Heat it up and pound it nice and flat to match the width and thickness of the existing tang and drill holes to match the existing tang holes. Heat it up and while red hot quench in oil and let cool in kitty litter (clean) Then let set in oven at 200 degrees for 1 hour. Rivot to the the existing holes and cut to length. Also before rivioting, get some JB Weld and spread between the two tangs and be generous with the JB weld around the married pieces after rivioting. I know it may sound unprofessional but I assure you it is very practical. Of all tangs and handles I JB Welded and rivoted, none ever came loose or broke.
Hope that helps.


Thanks for the advice....there's a lot of stuff there I have considerd.  Since I'll be making the handle from home made micarta it can be certainly be a bit ugly as far as the repair goes as it will all be covered in the end, of course.
