I put this together from a pile of parts that I bought off of eBay. The parts were (and most still are) a royal mess, but with some love and elbow grease I did end up with a solid and lovely old lockback. This is one of Ka-Bars that was made in Cleveland, Ohio after Cole purchased them. I am guessing, from what I have gathered, that this was made in the late 1960's to mid-1970's, based on the tang stamp.
The mark side scale (showing) had a big gaping crack in it that ran the length of knife, through the rocker pin (you can see it in this picture). I epoxied it together and then use some CA glue to fill in the crack, and then lots of sanding and polishing. You can still see it, but it is stable. I debated replacing the wood, but the old rosewood looked very nice otherwise, so I think of the crack as character
I am not sure what kind of stainless steel was used on these, but it takes a wicked sharp edge that will shave hair off of my arm.
