You've got to read Street Steel by Janich, the blade configuration has been bantered about on several previous posts. If you go to the search here at DRTV and just type in "tanto" you can find the previous posts, by Janich himself, weighing in on his very valid advice.
I think the consensus was a more traditional blade vs. Tanto design. However, to each his own, kinda like firearms.
Just my .02 cents, I know there was some very informative posts regarding blade design and SD applications going back to 09.
