I carried mine this morning - in dress slacks.
Carried all the way back in the right front pocket, it carries great - you don't know it is there.
I am not much more than average size - 6'2" 275 lbs - but this knife is not noticeable when carried clipped to my pocket.
It is slightly smaller than the 300, and carries much smaller in my opinion.
It sure is beefy, and like Czech - I love the "old school" pivot with the hex bolt, but the ZTVT makes the blade very smooth to operate in either direction.
Another thing that I notice right away, the detent ball is apparently very close to the edge of the lockbar, so when you disengage the lock and pivot the blade closed, the detent rides up on the blade tang very early in the motion, thus avoiding the "step" feeling you get on some other knives as the detent rides up on the tang later in the "stroke", if you will. This makes the 0909 feel even smoother operating; at least to me.
A great knife that will be a classic - stock up!
