Looks like a Jeff Freeman design and shares several design details with the Freeman Outdoor Gear 451 and other Freeman knives. The slant milling texture and the thumb inset in the blade look like they are right off a Freeman. Jeff Freeman worked for Gerber and designed a lot of their knives. If he is doing some design for KAI now, I hope to see a Freeman high end ZT. Gerber has some great designs, but Chinese imports have terripble steel and mediocre fit and finish. Those price points are unfortunately what most of the market wants.
