Got my Military today!
Initial impressions are extremely favorable. It felt a bit odd in the hand at first, because the only two other Spydercos I own are a Chinook 1 and an original Manix. Compared to those two knives, the Military almost felt TOO light.
The blade is wickedly sharp, sharper out of the box than the above mentioned knives. The grip is very comfortable, and fills the hand well in a variety of positions.
Fit and finish are excellent, on par with the other Spydercos I have owned and handled.
The light weight does not seem to detract from the strength of the knife, and it does seem to disappear one you put it in pocket. However, I do kind of enjoy the 'beefy' feeling of the Manix and Chinook. If one was made available with a lock back like those knives I would pick it up as well.
Over all, seems that this blade lives up to all the hype surrounding it.
