Okay, so, based on the behind the scenes look at the knives, it appears that there are actually two nearly identical designs for the Kill Knife. The only difference appears to be a small protrusion of the tang, on the blade-side, at the top of the handle. This protrusion could also be an optical illusion created by the different reflective qualities of the steel for the blade, the aluminum for the handle, and the fact that immediately above that area on the tan is the bevel for the blade, creating a visual disunion. Also, the only times it seems to exist are the times when the knife is turned slightly sharpened-side towards the camera in the behind the scenes stuff, which also might make the depth of the handle appear to be part of the tang.*
All of the stunt knives appear to have their tangs completely flush with the grip plates, so it's my working theory that the protrusion (if it is there) is a simple safety measure on the REAL, sharp knife to prevent the actor's hand from accidentally slipping forward onto the blade.
The question becomes which do you guys feel is more indicative of the design? Does having the stunt knives all flush mean that that's the way the designers want it to be viewed? Or does the fact that the actual knife might have the protrusion mean that THAT'S the way it should be.
I've made up a quick comparison between the two designs. Post and let Jimmy and me know which you feel is more accurate/you want more.
Also, just for fun, here's how big the kill knife (Using my scaling) would appear in my tiny, pale hands:
(I might as well have some fun while sitting at the computer for hours on end)

*I believe the protrusion is an optical illusion. I've now been frame-by-framing the behind the scenes video for about 40 minutes straight, and although I went back and forth originally, now, it appears to be the depth of the handle creating the look to my eye.
