The Kershaw Blur is a favorite among knife enthusiasts. The Blur has the build and performance of a great general purpose knife with everyday carry friendly attributes as well. The Ken Onion designed Blur is an assisted opening knife, just give the blade a push with the ambidextrous thumb stud and the Speed Safe technology finishes opening the blade! To close, just slide the liner lock to release the blade.

Buy this if safe panic opening is a must-have
William M. on Jul 25, 2021

I was walking my dog on the trails when it confronted a coyote. Things were tense and just in case I pulled out my pocket knife. In the panic while trying to do an opening on the liner lock like you see on YouTube vids, the knife flew out of my hand. Fortunately, the coyote had long retreated by the time I went to pick up the now-partially open knife. There were two fails: the force required to open the un-assisted liner lock with a stiff detent, was so great I accidentally flipped the whole knife out of my hand. Second, because my flipping energy went into flinging the knife away and not opening it with authority, it had failed to completely open. This made me realize why Kershaw calls its assisted opener Speed SAFE - I always thought that was a joke (the Safe part) because I feared accidental opening when loose-carrying in a jacket pocket. I never thought about the other side of things, that the assist-spring also makes sure the blade will completely open even with a weak start. Also, the pressure required to get the Speed Safe started is minimal compared to modern overly stiff detents. I had avoided Kershaw Speed Safe (or avoided carrying, not collecting) out of concerns it might be viewed as an illegal switchblade. .... Now, I carry the Blur in my right rear pocket pushed against the seam for safety. Since it is tip down, I know even if it somehow did get bumped or snagged out of fully closed, I won't stab my finger reaching for it. I know when I go to open it, it will snap open fast and fully lock up. I hope I never have to use it on a coyote (or cougar, they are showing up more and more) but at least it won't fly out of my hand. // P.S. the rubber grippy insert things are very helpful, but make inserting in pocket grabby. So I removed the clip, put a short section of Gorilla Tape underneath the contact point, and now fewer problems, until the Gorilla Tape starts to peel up (it's much stronger than slick electrician's tape, but still has its limits).

I bought two !
Mike M. on Sep 1, 2020

I bought this knife and after receiving it I realized this is one great knife. So I ordered a second ! If I could only have one knife this would be the one. This is just a basic do all knife. No frills, nothing fancy, its just works. Form and function at its best.

A damn good knife!
Dave G. on Jun 8, 2020

All I wanted was a damn good knife. I'm not a collector, and this was to be my one and only blade. I purchased MANY through Blade HQ -- Spydercos, Civivis, Kizers, Benchmades -- and returned them all... Except the S30V Blur! IMHO it's perfect in so many ways: size, weight, blade material, opening action, liner lock, scales. Light enough to EDC, heavy enough to do some work. My only complaint is the roughness of those darned thumb studs. And yes, I'll replace the clip with a deep carry. Definitely a classic!

Long term EDC!!!
Roger R. on Mar 31, 2019

I have been carrying this knife for umtysome yrs now! Can’t even remember! I’ve traded it out many times, but always seem to come back to it! Good steel, solid construction, and the Kershaw reliability!!!

Rugged EDC
Tyler K. on Mar 4, 2019

I was looking for a knife that was tough, easy to open with gloves and had a decent steel that would be able to withstand a lot of use and wet conditions. This knife meets all of those requirements and for a very reasonable price point.

Love this knife
Matt c. on Aug 24, 2018

Ive been carrying this knife every day for a year and a half and I've used it for everything from cutting foods at people's houses when their kitchen knives weren't sharp enough to cutting wooden steaks while camping and somehow ive never had to sharpen it and its still the sharpest knife I own

Great knife for the money
Donald M. on Jan 7, 2018

Really like this knife. S30V is really the only way to go. I do wish you could get a deep carry pocket clip for it but other then that great knife!

Exquizid cutlary
George R. on Jan 6, 2018

Great knife expesialy for the price I've had this blade for around 2 years now and still is decently sharp.

Good user
Gerald N. on Jan 6, 2018

This is the first and only Blur I have owned. Comfortable to use and carries well. The blade came very sharp and stays that way for a long time. The assist is good without being too strong to close one handed. It would be nice if it had a deeper carry clip but otherwise no complaints.

Great edc! but assisted opening unnecessary
Daniel b. on Sep 8, 2022

I got this to replace my cold steel that i always felt was too thick and hated carrying it. I love the profile; I've had this for 6 months and its much slimmer and fits more comfortably in my pocket. enough for me to forget about it most of the time. the blade steel is nice, I use this for what most people use pocketknives for, mostly simple everyday cutting tasks with the occasional witling down some marshmallow sticks when we do fires. I do have some issues with the assisted opening, any time ive dropped it its snapped right open which was eh to me, so I disengaged it and found that the bushings in this knife are faster and easier to open than with the assisted knife. it still has enough tension to stay closed but the force of overcoming the spring to initiate opening actually makes it slower and harder to deploy in my opinion. Id like to see a version of this that isn't spring assisted, so I don't have to void the warranty. I feel like spring assisted is fairly overrated anyways

Richard G. on Feb 4, 2018

One of the first knives I ever owned. I ended up purchasing it in many colors (black, red, od green and many steels (440A, Sandvic 12c27n, 14c28n, 154cm, S30V). I love the recurve blade and it was the first knife I owned with speed safe. The more knives I carried the more I found there were things I didn't like about this knife. With hard use the blade would develop play. The thumb stud is sharp and you tend to scratch your hand when putting you hand in your pocket. The handles were so aggressively textured they tore up a lot of my jean pockets. NOTE: These are issues with Blurs from 2012 and before. I haven't handled a newer Blur so some, if not all issues might have been fixed. Build quality: 4 stars Materials: 4 stars Aesthetics: 3 stars Personal likability: 3 stars

Good edc
