I just picked up a black and green scaled version yesterday. I agree with others about the logo and extra branding on the blade, but that aside it's a great folder.
The blade is of substantial thickness and the sharpest Benchmade I've come across--mine was "even with usual handling care and habits, it still nicked me unexpectedly" sharp.
The steel liners are skeletonized, I believe the jimped backspacer is steel as well. Between the liners, backspacer, G-10 grips and thick blade, it's a substantial knife and feels very solid in all aspects with typical Benchmade lockup and relatively smooth operation. It's kind of like the Presidio and Griptilian had a kid, then the kid took steroids.
Personally, I like heavy folders and thick blades, different strokes and folks and all that and the Bone Collector fits my bill, silly logos and all.
Best,
