I don't deserve a knife this nice, it is going to lead a sheltered life. It is really made for professionals that keep us safe, which I am not. The chance of my ever using it, even for self-defense, are slim. My world is pretty tame most of the time, so I suspect that I will carry it, sharpen it, and appreciate it, while using other knives for daily utility.
This knife is beautifully conceived and executed. It is the third Benchmade that I have purchased with the marvelous aluminum handle, which just feels and looks fantastic. Dimensions, balance are perfect. I am a little puzzled by the front-side-only sharpening strategy, but I have to trust the pros at Benchmade. Nothing about this knife strikes me as a "cut corner".
I have managed to make peace with the Boltaron sheath, clipping it to my belt horizontally in front. I am looking into other ways of carrying it, but this works the best for me initially.
This knife is so great, I have ordered its younger brother, the OTF Infidel. I can hardly wait to carry them both simultaneously, with maybe one or two other Benchmade knives as well. Hey, I have a lot of pockets.

I have one of these new fixed blade Infidel. It reads 'black class' on the box. I am not fond of the sheath, particularly the strap. On inspection, the edge is ground only on one side of the blade with a light polish on the other side. I thought this was a defect, but it turns out it is part of the design.
Why grind only on one side? Does it have something to do with D2 steel?
A nice dagger blade

I like this knife. The aluminum handle feels good in the hand, like it will not slip out of your hand during use. I did find the grip to be a bit small for my hands though. A quick wrap in paracord fixed this though. The snap strap on the sheath does nothing to secure the blade. But the knife snaps into the sheath nicely so there is no risk of it falling out .
