The Robeson 622246 jack is one of the most comfortable knives I have ever held. It just feels like an extension of your hand.
Robeson used a protective lacquer-like coating on their display knives.
I bought a scout/utility that had it, but it had flaked off in numerous places. The seller thought it was rust corrosion and sold it as such. I removed it with nail polish remover to reveal an absolutely mint knife.
It can be removed or left as part of the history of the knife.
I used to have one of those Indianapolis Paint And Color jacks. They also put that etch on a toenail and a jumbo sleeveboard whittler. To have all three would be a great subset to a collection, Indianapolis Paint And Color gave away some nice knives. Just think of the ones that spent their lives opening paint cans.
Nice stockman. Lots of life left it that one.
