Looking for a pocket ninja sword that can also blast out windows? No? What about glass coke bottles? Yes. Look no further...
As someone who owns a lot of knives (don't be alarmed) this is still one of my favorite dependable pieces. It's no secret that Kershaw makes good dependable well designed entry level knives. No one is going to confuse this with a Sebenza or a Strider model knife but this knife isn't trying to be that to begin with. I originally purchased this knife THREE years ago and with an occasional sharpening here and there this thing is still in great shape.Kershaw is to knives as Honda is to cars. You like that analogy? I know you do...The blade comes razor sharp out of the box, maybe not hair shaving sharp, but sharp enough. A little work on a stone or sharpener could easily get it there. Not the biggest fan of serrated blades but there is a time and place for them and for work having the serrated portion of the blade has been money i.e. cutting rope, twine, plastics, etc. However, a word to the wise I wouldn't use this knife to pry or anything like that as I could see potentially dinging up the point or edge of this knife.I'm personally a fan of Kershaw's Speedsafe system (no I don't work for them and no this isn't an advertisement but I won't say no to a sponsorship *wink wink). I like the quick decisive opening of Speedsafe knives with little to no effort. It's one of those mechanisms that will have you opening and closing your knife repeatedly like a creepy military veteran sitting in the corner of a waiting room muttering silently to himself.The handle is very grippy and won't slip out of your hands even if they're wet/damp...however, if you decide that you want to get crazy with the tanning oil at the beach and then want to cut open a bag of nuts with this knife I would probably wear some eye protection...Lastly, this knife does have the carbide tip glassbreaker. Have I used it? Oh yea...does it work? absolutely. Does breaking glass scratch, mar, and cause general imperfections on the knife handle? Yup. But how else are you going to let all the knife dorks and your tacticool buddies know that this isn't just some eye candy you keep in your pocket!

Best knife to date after 40 years of collecting
I’ve been collecting knives for over 40 years. I own Buck, Kershaw, GEC, Uncle Henry and whole host of made in USA knives. This Blur 1670 is by far the best. The knife is razor sharp out of the box. The Speed Safe feature is flawless and opens the knife with authority and purpose. The T6 aircraft aluminum body is strong and light weight despite the almost perfect overall weight of the knife. It incorporates a glass breaking tip on one scale which is polished, stout and sharp, perfect for emergency applications. The scales are moderately to heavily textured and ensure a positive grip. The thick Scandiv steel blade has a convex sway from the tip to about 2/3rds down the blade then transitions to an aggressive serrated profile, perfect for cutting rope and seatbelts. My knife is black with a black oxide coating on the blade.I own at least 25 knives and while they all excel in specific categories this Blur ticks all the boxes as an EDC and an excellent knife for Emergency Responders. I say that because I’m a retired Emergency Responder and wish I had this knife while I was on the job.If you’re looking for a made in the USA knife at a bargain price with excellent materials and dependable real life design features, then look no further. This is it! The sub $70.00 price point might sting a bit but you’ll not regret it.Well done Kershaw!GO USA!

An Awesome Pocket Kershaw with Glass Breaker... You Can't Go Wrong.
These are beautiful and simple knives. And they get the job done. I've been impressed how often I need it and how sharp the blade stays. This is my second one. BUT before looking like a knife crazy collector, I must add the disclaimer that this second knife has a glass breaker tip on the end. (Because if I ever come across a dog or child left in a hot car, I won't be hesitating to Kershaw their asses out of there! Though one must be cognizant of the proper legal channels for saving a living being from an overheated car.)For the price, it's in incredible knife. It fits in my hand wonderfully, almost ergonomically. I love the thumb opener on the side of the blade and that's ruined me for any other knife. No more two handing it. No more flicking to open. Well, I could go on and on, but I think I'll stop about here. It's awesome and Kershaw has made a life long fan out of me because of this knife and the reasonable price. Think about it... for pennies a day, you have yourself an awesome utility device.

Impressive right out of the box
Just received my knew knife...very impressive. Blade is sharp and seems solid. Grip is roughened so slipping in your grip is less likely to happen even in wet conditions. Time will tell but first impressions are excellent.

Excellent purchase choice - rescue tool and all around great resource
I love this knife. The handle is textured in such a way that the tool can be used in wet weather or dry without losing grip. The assisted open is a fantastic addition to have. Push the thumb studs and SNAP!! it is open and locked in place. I've used it to cut all sorts of stuff and am impressed with its ability to hold an edge. I particularly like the serrated portion: great for when you need to cut through rope or (God forbid) a seat belt. It has a pleasant heft to it and feels good in my hand. It is also easy, with a little practice, to close this knife one handed. The carbide tip is not messing around when it comes to breaking glass. This is an excellent rescue tool and all around resource to have on hand. My only "complaint" is that the carbide tip is a bit scratchy against the upper thigh when it's in your pocket. But for God's sake, don't let that deter you. And DON'T carry it blade side out. It WILL open if you rub up against something the wrong way, which is why the instructions tell you to keep it clipped in your pocket. I highly recommend this knife. LOVE IT.

Could be my holy grail of pocket knives
I was carrying a SOG Flash II pocket knife for 1.5 years. Somehow it got out of my pocket and I needed a replacement. I also own a Spyderco Tenacious but had not carried it too much as I really liked the spring loaded SAT feature of the SOG. But the execution and machining of the Spyderco was really well done and thought out, particularly the jimping at the back of the blade and the shape and honing. My thoughts were if Spyderco made a knife that had the SAT technology built into it, that would be my holy grail pocket knife. So I began asking on several different forums that I am a member of and someone mentioned the Kershaw Blur. I reviewed the knife extensively on youtube, saw that it had the SAT technology and the pier construction, saw that the handles were not plastic but a rubberized insert, and as a bonus you could get the knife in all black with glass break stud on the back edge of the handle. It also has an angled stud as part of the blade as a deployment assist. The edges of that stud are kinda sharp and if you repeatedly work the action, you might wear a hole into your skin. I did. You can reposition the very sturdy clip to either end of the knife. Here is where I'll knock off a star. The knife comes with the clip positioned on the opposite end of the glass break stud. You probably should leave it at that position. Although the knife is positioned opposite of the ideal position of where you might like the knife to be located in your hand if quickly drawing for a defensive deployment, keeping the glass break stud stowed in a point down position is imperative. The glass break stud is very sharp, it will cut/stab anything it comes in contact with. Reach for a wallet, it stabs you. Sit down in a car seat, it might cut the fabric. So it is a trade off, the stud could be useful in an emergency situation of breaking a car window but you now have to carry the knife in pocket clip backwards. It is now a question of pull/position the knife/deploy blade vs pull/deploy blade. With practice, one could become comfortable with the extra step involved. The risk is dropping/ fumbling the knife on a rapid deployment situation. The knife also has jimping in the liner lock and the back of the blade but neither are very useful, the jimping is very rounded and my thumb slides over it, so it provides very little grip.

Great product
I have only owned this knife since '06. Two lost to the sea while in CG. On my third now

Great quality for the price.
I bought this item as a gift. I have owned one of these knives for many years now, and I wanted to share the experience with a friend. The serrations on this knife are one of my favorite aspects of it. Unlike many serrations that are very jagged and pointy, these are slightly less aggressive. I have found they work much better than other serrations I have used in the past. They don't just snag and tear what you are trying to cut, but glide smoothly through thick straps etc.The assisted opening also works very well, and makes a satisfying noise when you open it.Unlike many "glass breaker" knives that just have a pointy piece of steel, the glass breaker on this knife is made of carbide. In order to break tempered glass you need something that is harder than the glass, and this works perfectly. It is very difficult to break glass with just a pointy piece of steel.Granted, this knife is not as well built as some knives which costs two to three times as much, but for a well built middle of the line knife this fits the bill.

Top, Erwartungen übertroffen!
Nach einiger Suche im Internet nach einem geeigneten Messer bin ich auf die Firma Kerschaw gestoßen.Auswahl gibt es ohne Ende, daher habe ich die Suche schnell eingegrenzt, es sollte einen Bereich mit Wellenschliff sowie eine Möglichkeit zu Verwendung als "Nothammer" haben.Zur Verabeitung:Absolut makellos, jedes Einzelteil passt perfekt zu den anderen. Der gesamte Eindruck ist durchaus elegant, speziell durch die dunkle Klinge und das geschwungene Design der Seiten. Diese sind sehr rau, dadurch hat man das Messer aber auch nasser sicher in der Hand. Im Prinzip fühlt es sich wie ein Schleifpapier mit Gummi überzogen.Die Klinge ist ordentlich scharf geschliffen, dennoch hält sie schon erstaunlich lange scharf. Offensichtlich wurde ein guter Kompromiss zwischen Schärfe und Haltbarkeit bereits in der Fabrik gewählt. Das selbe gilt für den Sägebereich, wobei ich diesen hauptsächlich für Seile/Taue verwende.Die Spitze zum Glassbrechen ist zweifellos sehr hart, aber nicht zu spitz, in der Hosentasche/am Gürtel kein Problem.Zum Handling:Eine Forderung war die Bedienung mit nur einer Hand, egal ob links oder rechts. Beides funktioniert problemlos, schnell und ohne zu starken "Rückstoß". Es öffnet sich nur unter Druck mit dem Daumen, daher habe ich keine Bedenken durch eine unabsichtliche Öffnung der Klinge. Es lieht gut in der Hand, die Größe würde ich, ausgenommen größere Männerhände, als optimal einstufen. Auch kleinere Hände können das Messer problemlos öffnen und führen.Der Clip ist relativ hart gefedert, was vollkommen in Ordung ist, so verliert man auch im laufen nie das Messer. Zudem lässt sich die Position des Clips an eine zweite verändern, eine Anleitung zur optimalen Postion liegt bei.Im Gesamten bin sehr zufrieden, die Erwartungen wurden allesamt erfüllt bzw zum Teil übertroffen.

Sehr Gutes Messer
Das Messer hält seine Schärfe wirklich lange, trotz täglicher Benutzung.Es liegt gut in der Hand und der Mechanismus ist schnell und nicht sehr schwer zu schließen.
