The Blur is equipped with a big, slightly recurved blade that’s ideal for multitasking. The blade shape offers both excellent slicing and piercing capabilities and the high-performance Sandvik 14C28N stainless blade steel offers corrosion resistance and hardness. It has a DLC (Diamond-Like Carbon) coated blade for extra corrosion resistance and enhanced looks.Handles have Trac-Tec grip-tape inserts for an extremely solid grip. The handle itself is durable 6061-T6 anodized aluminum, sometimes described as 'aircraft aluminum' since it is a common material used for aircraft fittings. But the main point is that it’s lightweight, extremely durable, and—when anodized—accepts a dye so we can create colored handles that are scratch resistant and extra tough. For easy one-handed opening, the Blur is equipped with SpeedSafe assisted opening. A short push on the thumbstud overcomes the resistance built into the torsion bar in the SpeedSafe mechanism. The SpeedSafe takes over and the blade moves out of the handle quickly and easily. One-handed opening is easy with SpeedSafe. The pocketclip is reversible for your choice of tip-up or tip-down carry. There’s even a pre-drilled lanyard hole.

I have hundreds of tactical folders to compare this knife to and it stands up superbly. It's build quality is outstanding, opens quickly and easily, quality of the steel is adequate, the blade shape is attractive and useful, the grip is comfortable and much improved over earlier version (they had sand paper, current version has thin rubber inserts), and Kershaw's service and support is perfect.
In my duty use in the military, I have used Blurs for several years and they always impress. For $55 you should buy several and give them as heirloom gifts. Other knives with these features and opening speed, including automatics like Microtech and ProTech, will cost three times as much. A great knife that will last forever with care.

I hate to feed into the mentality that causes knifemakers to hype their blades as "tactical," because the last thing we need to give lawmakers is another excuse to heroically protect us by banning the tools we carry. But the first and last thing I have to say about the Ken Onion Tactical Blur is that it is one fearsome knife.
A curved blade would be suited to your usual cutting and slicing applications, such as skinning mastodons and so on. This knife, on the other hand, has a chisel-like tanto point, which is ideal for thrusting effortlessly through beef ribs or car hoods. It would be equally at home cutting up cardboard boxes, linoleum flooring, or metal garbage cans.
Technically, this isn't a switchblade. Switchblades are bad. We know this because our lawmakers have heroically protected us by effectively banning them at various levels. This is only an ordinary liner-lock knife with spring-assisted opening. But if I ever found a switchblade with the deployment speed and cutting power of the Blur, I'd say it was quite a knife.
The blade is shaving-sharp from the factory, and the handle is lightweight but sturdy aluminum with some kind of gritty sandpaper-like stuff glued on to give a better grip should the knife become slippery with any sort of fluid. Use your imagination. I haven't tried shattering any cinderblocks with it yet, but it's sturdy enough to use as a yawara stick in a pinch.
Folded, the whole package can be palmed even in my small hands and feels much like a disposable lighter with a glandular problem. I don't even notice it in my hip pocket, which is where it rides whenever I happen to be wearing pants.
If walking around with something this fearsome seems too naughty for you, remember a couple of things. One is that you can buy it from The Wall for $55, and The Wall would not sell naughty things to naughty people. Another is that crimes, to my knowledge, are not generally committed with knives like these, but with such evil implements as kitchen knives, screwdrivers, and whatever happens to be lying around near the crime scene. Lastly, you will probably not need a knife this fast and ferocious, but if you do, you will *really* need it. And you'll have it.

Fun, cool, outstanding, fast, well built, ok ok I get it on with the review.
Best Tactical folder I own. here's why
Upside;
1. Fastest assisted opener I've seen. A little thumb pressure on the really well crafted thumb studs and "smack". Opens in a "blur".
2. Blade stregth is superb. Arrives sharp, stays sharp, and cuts with ease.
3. Perfect size. Extremely comfertable in the hand.
4. The grip is very good. An almost soft rubbery silicone grip tape along the outside will not allow you to let go.
5. Pre drilled holes for tip up or tip down carry.
6. If you get the Blur with the partially serrated edges, the serrations are wicked sharp.
7. Well built, put it through abuse fella's just don't get stupid with it.
Downside;
1. Thumb jimping is pretty weak, however, the grip tape works.
2. The pocket clip is reallllly tight. Tough to draw from the pocket without bringing your pocket with it.
Overall, I own several, buy it. Its great. It is the one knife I take everyday on duty. I refuse to leave my patrol car without it. Good job Kershaw.

It took me a minute to understand the right way to open this knife, it's not like the Chive or Leek. Once I did, OH YEAH; just push straight forward with your thumb and this thing is Black Lightning. The grip is such that you could hold onto the knife if it was covered in grease. I love all of Ken Onion's designs but this is the best one yet from Kershaw.

I've been in the Army active duty and reserve; enlisted and officer for 20 years. I'm currently working as a law enforcement officer. So, I've dealt with a lot of knives built for various purposes. Taking everything into account I would consider this one of the best knives I've owned. It has a great edge for doing day to day routine cutting boxes, 100 mile an hour tape, I cut slices of bannana bread with it today. However, with the spring loaded action and the sharpness of the blade I have no doubt it would be a great knife to defend your life with. I know, I know odds of that happening are probably slim to none, but like a previous reviewer said, "you will probably not need a knife this fast and ferocious, but if you do, you will *really* need it". 'Nuff said.

Short version: This is the first folder that I've owned that I have no complaints about.
I have owned three other, more expensive folders, one of which was a Boker with a ceramic blade. All of them had flaws. I expected this knife to have flaws as well, but there are none.
The assisted opening action is smooth and authoritative. The handle is rough, almost like Line-x or Rhino Liner truck bed liners. There is no chance it's slipping out of your hand.
The blade is razor sharp, and sturdy. It fits nicely in the handle when folded up so that it's not banging against the body sides.
The thumb studs are ambidextrous, and the pocket clip is tight. There's no falling off of your pants, and it's not sharp so it won't cut into the fabric.
The knife is lightweight, but sturdy. People are shocked when they ask me how much I paid for it and I tell them. This knife will be staying with me for quite a while!

The knife holds a good blade even after some abuse. The thumb button is a little small and a bit tough on the thumb after repeated openings but does open the knife very well. The textured handle provides a very good grip but works like sand paper on anything else in your pocket. If I lost it I would buy another one.

The Kershaw Ken Onion Black Blur Folding Knife with Speed Safe (smooth edge) exceeds its product claims. It is an extremely high quality item that can be held securely. With the speed safe design it can be opened VERY fast with one hand without posing any danger to the user even though the blade is extremely sharp. Its all-black design makes it look high-tech, and, as I use the included pocket clip, I frequently don't even realize that I'm carrying it despite its size. My only problem was that I had to move the supplied pocket clip from one end of the knife to the other (I'm left-handed), and I had some trouble locating the T6 (very small) Torx screwdriver to do this with. When I need another knife, I'm looking at the Kershaw product line first, and hopefully last. I have a special sharpener to sharpen it at the correct 20 degree angle:Furi Ozitech Diamond Fingers Pro Knife Sharpener

To be honest I was a little taken a back by its size out of the box. This is a serious blade, at first I was really hesitant to wear it in public. I've since gotten use to it. No one has made any comments about it being over the top. This being said, I live in the county side where carrying a large pocket knife is not abnormal.
Two months in, my initial unease has faded. This is a fantastic knife, the grip feels natural and sure, even when wet. It's faster and more reliable than any switch blade could be, and it's legal. It keeps its edge very well, opens perfectly, every time and hypothetically speaking it will do the job if you're ever in a dark alley and need to make a point about the cons of mugging a perfect stranger.*****
It's a beautiful and effective tool, I highly recommend it to anyone looking for a larger sized, quick opening pocket knife.
*Two months into owning this knife, I was attacked and put to the ground in a choke hold, when my hand found this knife, you have no idea how relived I was. It opened perfectly and quickly with one hand,
(I was pinned face down) All it took was a minor cut to get the guy off me, I was able to hold him off until help arrived.
For those of you who think it can't happen, be prepared.

This is my first adventure in the world of the higher quality knives after years of many cheaper knives. I am in the public safety field and purchased the version with the partially serrated blade for an easier time cutting seatbelts, etc. The blur is just the right size for a host of chores or last ditch self defense. Some have mentioned that it is too big for every day carry - I disagree. I've found that the knife sits in my duty pants pocket and jeans pockets just fine. The assisted opening is a very nice feature. I opened it several hundred times and the action seemed to smoothen out to perfection and the function is logical. No worries about the blade opening accidentally even without a safety due to the design. I never did understand why you would purchase an assisted opener for speed and then use a safety which slows the process. The blade came extremely sharp and the blade appears very high quality and able to hold its edge. I initially bought this knife for work, but now carry it when I'm not working as well. I'm not typically a guy to carry a knife everywhere I go, but I've been converted. There has been mention in other reviews about the handle texture. Overall, I like the texture (a plasticy, rubbery cross breed). It provides for a secure grip, but I could see the texture eating one's jeans pocket edge. However, it works nice in tandem with the clip making losing the knife less likely. There is no play in the blade once locked in place. The liner lock is not exotic, but works reliably which is a plus. I would buy this one again for sure. I might even try a couple of the other blade configuations.
