Whereas the blade itself is flat ground. Very complex geometry. He says it's done that way to make the tip strong so you stab through things. While the remainder/belly of the blade is evenly flat ground. So it can stab through steel drums and still cut cheese. On further reasoning, this makes sense. A flat ground tip is more prone to breaking at his or any other maker's thinness of blade if stabbed through a steel drum. the chisel tip adds material to the tip area.
On my folder that I just sold to Dirk, when the knife is folded and you look at the blade, it appears uncentered in the folded position, looking at the tip alone. But if you look closer, the blade belly/edge is completely centered between the scales. Only the tip appears off because there is more material on one side forming the top of the chisel tip.
One of the only knives that I've seen with two types of grinds on one blade.
