Kamagong, that second model, in that bone, was far and away the hottest seller of all my HJs. 75 virtually flew out the door. I think Vintage knives, and maybe Cumberland are the only ones that may have a couple left. The only complaint was the stiffness of the punch. On the first model I designed, that looks like the Robeson above, some guy was using the punch a lot, and closed it on a finger and cut himself pretty good. He was man enough to admit he was abusing it (dulled, so pushing too hard!), but I got paranoid, and asked Bill at Queen to keep it "stiff" for safety on this next model. Hard to open, but it stays open when you are using it. A punch is not like a blade. You change directions with it if you are not super careful, just by the way you twist it. It is not heat-treated as hard as the blade, to retain toughness!
The first model, like the robeson, but in stainless steel;
A pretty knife, in stainless though. I used one for a while, and it took a good edge. I was on them about the heat-treat, so I think they are very good.
The second model, all in 1095 like Kamagongs:
Only two were made in stag. I should have done a lot more. The candy stripes were made from two batches of cell, and one of them off-gassed; bummer

!! The Ebony ones (not shown) also sold like hotcakes.
The third model, the equal end, turned out not to be as desirable to most people as the second model which was a regular jack. But far and away, it has the best punch! It is a marvel of function, and very controllable for the size of hole you want to make. Takes a little practice to hone those punches, but they all three of them work well. Again, all in 1095;
Two prototypes, and a pre-production sample.
