The K390 Urban has been carried and used quite often at work the past 2 months. It's cut lots of cardboard, plastic banding, packing tape, and has even shaved wood from the cabinets we build. I finally got around to cleaning all the adhesive and grime off the blade and was surprised that isn't a mark on it. I've touched it up on the SM a couple times but it seems to stay reasonably sharp through a lot of use. I would say this knife provides excellent bang for the buck. If you've been considering buying one of these I'd highly recommend grabbing one before they're gone. I'll be interested in seeing how the S110V UKPK compares.
