John Primble Belknap HDW. & MFG. Harness Jack, circa 1940-1968, 3 & 3/16 inches closed.
I almost passed on this ole Primble Harness Jack. You can see it is a bit of challenge in the bottom picture here, where someone had apparently scraped both sides of the blade across a stone and the bulged burr of metal in the long pull slot (nick). After a lot of thought and the reality that I might not ever find an old J. Primble Harness Jack in comparable condition, I purchased it, with the thought I could rescue it and make it look like I wanted it to look.
Upon arrival, I examined it closely and decided I should send it back - too much work. I laid it aside and thought on it for a few hours. It had some positive things going for it. The size, at 3 & 3/16 inches closed, was wonderful. Both blades were extremely full, great snap and function on both, beautiful reddish brown jigged bone on both sides, nice shield, and would be a great addition to help slowly fill my old Primble cabinet. The biggest challenge was the large bump of metal in the pull slot.
After having my lunch and a lot of thought in a short period of a few hours, I decided to keep it and give it some time. I ended up working on the ole knife for nearly two and a half days, getting the slot cleaned up, some hard "pecks" out of a few of the bolsters and one bad "peck" on the shield. A lot of soft rubbing on the blades to get the sharpening marks out and it ended up very pretty to my eyes. The sharpening marks were not all that deep and a minimal amount of material was removed to smooth up and satin finish the main blade.
I finished it off by introducing a patina inside the long pull nick and on the tang stamp. I lightly sanded the tang patina, to leave black highlights inside the tang letters. I have not decided if I will introduce a patina on the blades. I have a set of curved mini files on order to hopefully finish a small place at the end of the pull slot. I will then decide on a forced patina. I kind of like it the way it is.
I went to bed with sore fingers last night and left the harness jack on the butcher block in my kitchen, next to some of my old coins.

When I woke this morning and walked through my kitchen, the morning light was just right, shining across the table and the old harness jack just looked so beautiful. I recall thinking, it was well worth the effort.
