I have one. Got it for around $10 delivered on ebay. I was prepared to hate it. But I like it quite a bit.
It's a decent size, approx 4" closed, 7" opened, 1/2" thick, not including the pocketclip. No lock, it's a slipjoint. With an oval hole allowing for one hand opening. Stainless steel liners, molded plastic scales with nice checkering. All screws are secure, the pivot without excess slop. The blade is a sheepsfoot shape, with a straight cutting edge, of 420J2. The grind is unusual and asymmetrical, hollow sabre grind on one side with no secondary edge bevel, and sabre grind on the other, with a wide secondary bevel. Upon closing the knife, the latter side of the blade contacts a sprung abrasive-embedded metal strip, presumably diamond. The result is the blade gets a quick, toothy sharpening swipe with each open and closing on one side of the blade.
The result of sharpening only one side of the blade produces a toothy burr on the opposite side. My instinct is to take out the stones and sharpen the blade properly. However, I've resisted, allowing the knife to perform as designed. And the performance has turned out satisfactory. Breaking down cardboard boxes goes surprisingly well. This knife isn't a push cutter. But it's a very nice slicer, as the toothy edge would suggest. Comfortable and secure in the hand. I'd think the burr would lead to problems, but it seems to hold up ok and seems integral to the way it's supposed to perform.
I'd say this would be a good knife for folks who don't particularly know or care about sharpening knives. The steel is soft, the burr more durable than expected. I suppose a dull Edgie could be restored to usability by simply opening and closing a few times. Opening one handed may not be for all, as the backspring offers more resistance than most one handed openers provide. I found the edges of the hole a bit sharp, but not enough to cut my skin. Pocket clip works well, rides somewhat high, right handed tip down only. No rivets, the knife could presumable be taken apart.
What would I improve? I'd like to see a bit nicer steel used. The 420J2 hasn't really disappointed me, but I'd like to see something a little bit harder. The blade, at .092", could stand to be a thinner, more efficient slicer. A half stop would be nice an just about any slipjoint. Particularly on a knife like this featuring one hand opening, and presumably, one hand closing. I suppose some folks would like a lock. I'm perfectly satisfied with slipjoints. There's no lanyard hole, but I don't think I miss one on this knife.
This is a novel knife that offers some unusual characteristics I very much like, pocket clip, one hand opening, slipjoint. And one that is growing on me, the self sharpening ability.
