About CRKT Edgie Self Sharpening Knife

CR6442: Self Sharpening “Edgie ” Folder w/2.9″ Plain Edge from Columbia River

This CR6442 self sharpening edgie knife is a utility folder that sharpens itself! It has an internal diamond strip that hones the high-carbon steel blades every time they go in and out. CR6442 exhibits a sturdy InterFrame build and comes with a stainless steel clip for hanging inside your pockets or against clothes. It has a handle length of 10.5 cm when closed and the total length while open is around 17.8cm. This tiny beast weighs around 108 grams and is one of the budget oriented knifes which is great for daily use. This knife has a patented design and is the brainchild of Maj. Howard Pope ( USAR Ret.). I must say he has put a lot of hard work into its design and working mechanism.

The Edgie is an affordable prototype of high priced similar function knifes. It has a broad appeal and the stylish curve looks simple. As I said before, a 400-grit diamond-coated spring sharpener is present inside the folder frame. It stands at the right place such that every time the knife goes in and out of the folder it gets a sharpening stroke from the spring. So sharp that it precisely cuts through its prey and comes out clean.

Therefore, it gives you some real time off from sitting and sharpening your knife with the help of stones and wheels. This blade is perfect for people who use it constantly and indulge in long working sessions. If you are a person who loves outdoors then this knife can be a handy tool.

The steel blades have a satin finish and have a full width spine that literally cuts deep down. Made of high-carbon stainless steel it looks simply amazing with the dual hollow grinds and the single cutting edge. This single cutting edge is so sharp that you can pierce easily through cardboards, ropes, and even juicy veggies with the perfect slices. This micro-serration is possible to due to the internal sharpening mechanism.

Features of CRKT Edgie Knife

CRKT brand is so popular and who does not love to own a masterpiece from their roof. They have all sorts of knifes designed by expert toolmakers. They have great picks when it comes to EDC knifes.

I have always wanted a CRKT EDC knife but never had the time to buy one or let’s say used my old knife itself. I had to sharpen it every time I use and then the same thing over and again. The reason for purchasing this knife was because it has the self-sharpening stuff that tempted me to get one.

I ordered a piece and I received a small neatly finished cardboard box. The knife comes with a decent package with a CRKT label imprinted on it. The interesting thing is that you get a catalog that tells you how to use the knife in various action modes.

When I held it for the first time, I felt like having something that looked sleek and stylish. It is lightweight and perfectly rests in my hand. I never felt like I was holding something extra in my hand with difficulty. It was easy to use as I just made some moves in the air.

This knife has a pocket clip that I actually liked. It stands on one side and does not switch to the other side. You can actually clip it to your pockets or gears while at work. It is simple clings on easily. If you do not want the clip then you can simply remove it and keep aside. The knife is easy to hold even when the pocket clip is on so you do not really have to bother about it.

The CRKT EDC knife  knife has the perfect mix of thickness and thinness that it easily fits into the hand while at work. When you put in the pockets, it seems to be small and it is easy to pull out. The zytel handle has a checkered design that provides the right grip. Whether your hands are wet or dry you can easily pull the knife along and get with your work. It does not slip off as the reinforced nylon fiber handle gives a sturdy grip. The dual hollow grinds present on one-side cuts through thin and thick materials just like that.

I tried cutting paper with the help of this and it was cleanly doing its job. It also cuts through thick leather quite smoothly. Even though it does these with the help of dual hollow grinds, I felt it was not of much use. I would not use a knife to cut through paper and other stuffs. This feature is perfect for those who are crazy about knifes and pick it for every single job.

Again, beware with this knife because it is not that easy to use at the first time you hold it. It has a slip joint action that works steadily. If you do not use the knife properly, there are chances that you get a cut in your hand when it closes back. So make sure to get some practice before using this knife. My friends have this knife and it is from them I knew about this beast. It has a great profile and stylish length of 17.8 cm while wide open. It has the perfect size and not too long. I love this knife and one of the best EDC knives I have ever seen.

The self-sharpening feature is what I liked the most as I can go around my garden and cut through the ropes and unwanted stuffs without sharpening. I carry it almost everywhere I go right inside my pockets. It does not slip of and holds tight on to my pant pockets without hurting me. It goes in and out the folder frame with a little tightness. However, once you get used to this knife you can easily pull it on and off the folder. This knife has many features that you can find in high priced versions. It has a simple design with almost all features you want. I am not sure if this one is the best but it is simply not like the rest and offers something much better than other brands. For the price and features this knife is a sure hit worth buying.
