6442 description
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.

The Original CRKT Edgie is a single-edged utility knife. The 2.875" high-carbon stainless steel blade in satin finish features a strong full-width spine. For strength and long life, we've used our InterFrame build, with two stainless steel liners and stainless steel back spring, all in satin finish. The injection-molded glass filled nylon scales have castellations at the spine and a checkered inset pattern to enhance grip.

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 to why the blades cut through fibrous materials so effectively.

The Edgie features a removable stainless steel clip in satin finish.

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.*U.S Patent No. 6,643,934b2

The Edgie is a great knife. The self sharpening feature is great. The only complaint I have is that the blade material is a bit soft. As Marine Engineer I work on steel hulled boats. I found that when I dropped the knife with the blade opened and it hit a steel framing it dented the blade. It still stayed sharp but with a small chip in the blade. I love the knife and recommend it to anyone. Darrell

Exactly as advertised and is always incredibly sharp. Couldn't be more pleased with the purchase.

the Knife is sharp and does hold a good edge. However, it is a bit thick for some pocket carry. It requires some dexterity, but it is possible to open with one hand. The lack of a lock isn't a problem, and the knife does stay securely open when in use. The quality, fit, finish, and overall appearance of this knife is very good. When push comes to shove, I would recommend it for light to medium tasks as a utility knife.

This is one of the sharpest knife I have ever seen. I like the design for size to carry in pocket. The blade stays open even though not a lock-back. Stays sharp constantly. ROSS

Excellent knife. I use it several times a day. I never have to worry about sharpening it. It is always sharp. It is just right for the pocket. Very handy. Chuck Jenkins

Fabulous product. Knife is larger than I expected, not quite an edc, but a very nice knife. Though there is no locking mechanism, the blade is stiff, and is not too easy to accidentally close when openned. Blade is very sharp, and the open/close sharpenning system works without a hitch. Highly recommended.

This knife is fantastic. I have never used a knife that continues to stay as shape as the day I bought it. CRKT is my new favorite knife company and I am looking forward to doing business with them again.

This is a great knife. Very sharp out of the box, good looking, and easy to use. The only shortcoming is the lack of a locking mechanism but it really isn't that big of an issue if the knife is handled properly. Its a great knife for everyday carry.

I love this knife. The blade edge did need some polishing out of the box but once the roughness was smoothed out it has held an edge like no other knife I've ever had. Excellent fit and finish. A locking mechanism would be a nice addition but unless you're misusing it it's absence isn't a problem. The Edgie is now my daily carry knife.
