So I have used and abused this knife now for about 3 solid weeks! I've processed wood, gutted some small game, carved wooden birthday gifts with it, cut open over 50 bags of quickrete cement mix, cut down several cardboard boxes, and it still holds a pretty sharp edge. After each days worth of hard work, I simply greased it down with a little gun oil, wiped it off, and put it back in its sheath. I have used this knife in just about every environment - from the blazing heat of the Mojave desert, to the beautiful redwoods of northern California, to the frigid parts of Canada, and then some! As long as you take proper care of this knife after each use, it'll last you a good long while!
I don't prefer the sheath too much, but it has served me well thus far and is still in pretty decent condition. I must say that I prefer this sheath over the older sheaths simply for the fact that I can actually put it on my belt without feeling I have to stick a thread through an eye of a needle.
Overall, I love this knife and it didn't cost me a fortune! I've tucked away all my other knives since receiving this one. I would suggest this knife to anyone who is much an adventurer as I am or even for the general "Joe" who has get some things "cut up" - this is definitely a great cutting tool and is certainly worth every penny and a bag of cookies. Hope you get to enjoy this as much as I have!
