i voted for the persistance, i recently gave my brother my persistance as a gift, barely used it wasnt for lack of abilities, i have a tenacious and felt the persistance was more sheeple friendly though my brother thought it was a pretty large blade. hes not a knife person. So this in some ways flys in the face of my choice, some people are likely to consider even the persistance to be a large blade. personally i think its plenty long enough for edc, though not a huge difference compared to the tenacious. probubly falls smack in the middle of what most would consider ideal edc size blade and overall weight. he fact that the tenacious and persistance are built like tanks. they can handle it imo. i often use my tenacious for my work edc, but would prefer the persistance due to size/weight a bit more, not so much that im going to buy another one just yet though.
