Wow. I can't believe no one is coming to the Buck/Strider's defense. I'll take a crack. SIFU1A is right about the sheath; it's not the kind of thing you'd carry in civilization. Way too big. I don't think an aftermarket sheath would change anything; this knife is just a handful - only medium long, but very wide.
The blade is not Strider's standard 1/4", it's a bit thinner (maybe 0.19 inches), but after handling this knife, I can't imagine that anyone really needs a full 1/4" thick blade on a knife this size. This knife is very stout, and surpringly sharp, as I found out when I nicked myself oiling the edge for the first time. The G-10 slabs feel very abrasive when you first handle the knife but I learned to appreciate the grippiness, and the ergonomics are excellent for a knife this size. If you are tactically-minded, this knife is very well balanced and the butt end of the handle is a serious impact weapon in the standard or inverted grips.
I'm not a "collector" myself, so real Striders aren't worth the price of admission because I'll never need a full-on Spec-Ops tool. For most users, a full 1/4" blade is probably more of a hindrance than an advantage. The Buck/Strider is pricey, but you're getting almost all of the functionality of a real Strider at a bit of a discount, and you may not even be able to get your hands on the Strider of your choice, at least not without a wait.
