That is a trail knife. Christian has one, a few others do, too. Christian's is the one in the TK article.
In this case, it's an order for a forum member, but there's 3 other in progress. nominally .23 through the tang, though I sometimes thin that down some, I like the balancing weight. Distal taper and full convex grind through the blade, which makes it not too massive (but beefy enough for heavy chopping). 5160, about 7-8 inch blades, with generous extra length handles for chopping. The black one in the fighting knife thread is the thinly disguised military variant. (though I think I'm going to do it in bvrown gunkote as a regular thing. But the oxpho blue is NICE stuff)
