Being a HUGE FAN of the Emerson/Perrin LaGriffe and Mr. Perrin's neat work in general, I have to say that is going to be a must-have item if it is ever produced. That has the capability of being a rage around this place.
Up until now, the Masters of Defense Scorpion was my second favorite knife behind the Emerson/Perrin LaGriffe, this one just beat the MOD Scorpion hands down and any of them are better than the Microtech Medallion thingy...haha!
[Excellent quality on the MT, I just don't care for it, I think part of it has to do with power and the defensive nature of neck knives in general. You want something small and comfortable to carry and has the ability to cut much more than size would hint at! That's why I like the little hook-blade knives like the two I cited and this one from Spyderco [Proto] has just enough hook on the end to work very well.]
Seriously, this is a very cool neck knife, to say the least.
