CR6444B: Edgie™ 2
Columbia River Knife & Tool

Now there are two patented* knives that sharpen themselves, thanks to inventor Maj. Howard Pope and knifemaker Steve Jernigan.

Since the dawn of human history, man has dreamed of a knife that would sharpen itself during normal use. Here it is, the patented* brainchild of inventor Maj. Howard Pope (USAR Ret.), who collaborated with custom knifemaker and Knifemakers' Guild member Steve Jernigan. We call it the Edgie™ line, because they hone their edges every time they are opened or closed.

The secret is diamond-coated spring sharpeners built into the folder frames, placed at the precise angle to give the blades a sharpening stroke as they are closed and opened. Not only do you never need to sharpen the Edgie blade with stones or wheels, but you should not, because it may alter the blade's proper self-sharpening edge angle. Of course, it is important during a long cutting work session to periodically open and close the blade to maintain the edge.

A note about the cutting edge. The diamond sharpening strips cause a tiny burr to form, acting as a microserration, which helps cutting action. This makes the Edgie tops for cutting cardboard boxes, rope, cord, garden stalks, and even ripe tomatoes. The more you sharpen Edgie models, the more pronounced this microserration honing becomes. For those who are used to a traditional Razor-Sharp edge, it may be disconcerting, but it is the secret of why the blades cut through fibrous materials so effectively.

All Edgie models feature removable stainless steel clips in satin finish.

Edgie™ 2. Steve Jernigan came up with a dual-edged Edgie lockback with a 3.25" blade. The "American Eagle Wharncliffe" blade grind tapers at the tip for better penetration and much easier cutting of thick materials such as corrugated cardboard.

Again, the frame is superstrong thanks to our stainless steel InterFrame build with Zytel scales. A textured surface and soft grooved TPR insert give excellent grip under all conditions.available.

The long blade slot allows easy one-hand opening. The lockback release is at the butt for exceptional lockup safety.

That's the Edgie story. It's not too glamorous, just a tale of affordable and tough little work knives designed to take a lot of use and stay sharp.

Pros: Lock Type, Ease of Opening, Lock Ease of Use, Blade Sharpness, None
Cons: Pocket Clip, Overall Quality
One of my favorite EDCs
This knife would have received a 5 had it arrived with fewer "raw edges". The blade release and the clip both were installed with NO de-burr grinding/polishing prior to assembly. Saying that, I love the knife and with about 5 minutes filing or grinding on the sharp edges they are smooth as a babies.... I have purchased 4 or 5 of them and give them as gifts, as well as carry one regularly. Be aware that the self-sharpening feature leaves the blade with almost a serrated appearance. Don't polish that off, that's what makes the thing so dang sharp.

Nice Knife
I bought this to add to my collection and to see how the self sharpening feature works. Overall it is a high quality knife and is indeed quite sharp. I have just started carrying it so I will see how it holds up.
