As somebody who makes things for a living, I agree with JNewell. To prove us wrong all you have to do is go ahead and make it happen, then post some photos of the finished product. Go ahead, it's easy!The hardest part would be splitting the handle (after you get the blade and handle separated). You could then send the handle halves out to be rehardened, unless you have the equipment. To split the handles you would need super specialized tools, none of which I know. It would really be easier to find a mule with a ruined blade, and take the handle portion of that for the other half of yours, or get some 420 handle pieces fabricated, then add your own scales.
