Initial Impressions: Awesome!

I haven't put this knife through serious use, but I am an avid collector of knives with more folders and fixed blades than I can keep track of. This knife came shaving sharp out of the box. It feels awesome in hand, both holding the handle with a full grip and with a finger on the choil. The only thing I was super fond of was the snap retention. Luckily, you can remove the strapping leather strap. I was attracted to the concept of this for the sheath, but did not like how hard it was to undo one handed. I am knocking a star off for this
