I think what is considered a "common" pocket knife is really up in the air. To me, my regular carry of a
CRKT M16-14SF is a regular ol' pocket knife. However, I can see how others would not see it that way, because of the hilted , nearly 4" blade.
Since I have my FL CCW, I don't have to worry about different opinions on how much of a "common" pocket knife that particular blade is, should the issue come up.
