I don't know a lot about knife techniques, but the Kabar TDI intuitively seems like it would be easier to learn. Good price and shape is a bit more adaptable to concealment.
That is one specific knife I recommended to a Deputy as a "Boot Knife", something he is VERY adamant about getting. When he asked me why, I told him it could be used for stabbing, and slashing, once again the gross motor skills thing. just grab it in your fist and start punching. And I have tried to talk him out of a boot knife, saying one on the back side of his duty belt, accessible to either hand would be more preferable, and the TDI would work that way as well. I might mention that he wants this knife in addition to the folder he normally carries.
