The reaction I've gotten from people on this knife has been very favorable. It's interesting enough on first glance that non-knife people are not scared by it nor are afraid to use it...that's a good thing!
This is the real meat, how the knife functions as a knife: It's great! I've used it for all sorts of minor cuting chores around school, as well as food and it's begged for more. The thin edge holds a nice sharp edge, and is easy to keep sharp on my Spyderco Sharpmaker. The handly is comfortable during extended use(Stripping about 8' of copper wire) and I never felt the slightest slippage. With it's flat grind, and thin edge, I've even been using it as a bread knife.
In carrying it around I've noticed something interesting, the carbon-fiber handles are grippy, and hard enough that they have started to wear the outer layer of copper off the rivits on my jeans. It's not enough damage to be noticable on the jeans, but on the handle is a small area where the copper is visable. Not a bug, more of an undocumented feature. My one suggestion to improve the knife would deal with the sheath, I think it would benifit from some type of metal throat, alligning the knife to insert it takes two hands, which is inconvinent.
I can say, without reservation that this knife is both a beautiful piece of art, as well as a functional tool, and that Jens is a maker to buy from now, before his prices better reflect his abilities.
