Kershaw Knives
This is one of the original Kershaw Blurs, the Blur that started it all.

Like all Blurs, it's 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. The black Blur has a DLC (Diamond-Like Carbon) coated blade for extra corrosion resistance and enhanced looks.

This black Blur has, as you might expect, black handles with Trac-Tec grip-tape handle 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, scratch resistant and extra tough.

For easy one-handed opening, the Blur is equipped with SpeedSafe assisted opening. A short push on the thumb stud 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 pocket clip is reversible for your choice of tip-up or tip-down carry. There's even a pre-drilled lanyard hole.

An exceptional EDC knife
I own quite a number of Keyshawn knives, and have liked every one. From their cheaper knives made in China, to their US-made ones, they’ve all bee good. And, I’m a big Ken Onion fan. Then I began buying Kershaw’s big brothers, ZT knives. They’re all that they’re cracked up to be - stout, overbuilt, reliable, excellent knives. But, they can be heavy, and I’ve come to like assisted-openers. So I came back to Kershaw, and have bought 5-6 of their assisted-opening knives. And then, I found the Blur. I have a new favorite knife. This fits your hand perfectly, comes razor sharp, good steel. The aluminum handle is strong, and the inserts give a superb grip. I love the blade, the thumb studs, basically everything. I’ve ordered more, and will continue buying this model. If I have one complaint, it’s the pocket clip. It could and should be improved. I carry tip-up, so I began to remove the screws to reverse it. Sadly, one screw has stripped a bit, so until I get a new bit, I’ll leave it for now. Amazing knife. You’ll never regret buying one.

Poor Lock up?
I"m an electrician and i have used this knife for over six months of hard every day use such as stripping cables, cutting ropes, and prying stuff open and even used it to baton cut some fire wood while camping. I have honestly not had the time nor need to even sharpen it yet but it is still very sharp. As for the peeps who claim the lock is week is BS or they simply got a bad knife, it happens even with 200$ and up customs and big run production knifes like ZT's, check Youtube on ZT spine test's. First thing I did with mine after flipping it a hundred times was to wack it on my work bench a dozen times, no fails not ones and after 6 months of HARD use and EDC it still fires open quick and secure every time. weak lock my A-S. If you make a 50 thousand of them your going to put out a bad one and if you spend 4 times the money Bench Made or a ZT you still have the chance of getting a dud that cost you 4 times the cost of a Blur. your call. PS. I just checked it for sharpness and it is dull for paper shaving so it's time to buy a new one and pass this on down to my son so I can teach him how to sharpen knifes. It's only 60 bucks and he loves it so it's win win.

One of the Best knives I own hands down!
I’ve used some of the best knives from all over the world while I was in service, including the “original black knife” by OX & many others, but I’ll be honest with you this Kershaw 1670BLK is way up there. In fact the Kershaw I like much better, it has better size and weight compared to the much more expensive knives. I can’t and won’t tell everything this knife has been though, but if only this knife could talk!I own several Kershaw knives however the 1670BLK I really got lucky on.
