Do you mean chisel grind (edge ground on one side with the other side vertical) or are you referring to a tanto primary blade profile? I don't think SRKW will spend any hard earned R&D $$$ on either one of those designs. And to be perfectly honest I hope they don't. The Mini, SRKW's only tanto to date never made into production and I chisel grinds just aren't that popular. I don't find either to be practical for general use, but if you are looking at this from a military perspective, I guess they have their purpose. I had an Emerson CQC-7 tanto folder and I just couldn't find much use for it. And that blade profile in a steel like S30V is just destined to snap under lateral prying pressure. I don't think you'll see an SR-101 folder (or INFI for that matter) coming out of Wauseon any time soon, if ever. As far as we all know the Rat Trap is going to be our only fix for an Ohioan folder.
That said the Rat Trap is a superb folder. Solid lockup, excellent craftsmanship, S30V and a KILLER factory edge. I love mine and as you can see from the prices they go for (last one on Ebay went for $256) they are highly sought after.
