This is no battle knife, it is fleet and slight.
The slim cross section is sufficient to ensure it is able to cut and slice, and the back of it is flat, as with its smaller folding sibling, which gives it an even slighter profile. The blade is stiff, even for its thickness, which I suspect is due to the steel and temper, but I wouldn't want to use it as a pry bar. Best leave that to actual pry-bars, frankly. I have been able to punch holes in cans for drainage however, and the finger notch, and thumb-groves on the spine make for a very sturdy and secure grip, even when wet. There is a nut affixed to the blade around the midline acts as the friction lock to keep the knife firmly in its Zytel sheath, as well as being a good rest point for the thumb during delicate cutting.
Unfortunately, CRKT discontinued the Stiff K.I.S.S. a number of years ago, and whilst they are still available online, I am sorry to have heard that. This is a beautiful piece of steel, and as I've said, it comes out to play whenever I go adventuring. Rope, salami, packets, jugs or cybermats, this is a blade not to be left behind.
