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.

The 1670BLK Blur features a tactical black finished blade with a plain edge and an anodized aluminum handle with Trac-Tek inserts for superior gripping power in all conditions. Black reversible pocket clip for tip-up or down carry.

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.

This knife is great! The action is smooth, the lock up is solid, it feels substantial but not heavy, perfect centering, great blade steel, and the coating seems durable. Like most people here I have a knife addiction but since i got this one 4 months ago I haven't purchased any other knife. It's a solid EDC that i can count on yet disappears in my pocket. If you're on the fence, buy it. You won't regret it.

The only ding i can give this knife is on the pocket clip. My preference is for deep carry and the stock clip makes it ride a bit too high for me. This was easily solved with an after market titanium clip.
Great knife

I have the old version of this blur. The date on the blade says sep 06. The Blur is kinda big for an EDC but not bad. When it is in your pocket it feels lighter than it is. Great ergonomics, and keeps a good edge. It's held up great for the longest time, but about a year ago the spring mechanism broke leaving the knife useless. Insted of sending the knife to Kershaw to get it fixed I took it apart and got rid of the spring mechanism. Without the assisted opening, the Blur still works great and is one of the smoothest opening knives I've ever felt. 10/10 awesome, indestructible knife.
Good work knife

First "expensive" knife I have owned. Great texture. Provides extreme grip when your hands might be wet or slicked up with oil etc. The assisted opening helps when you only have one hand free and need to cut quickly.

There are a lot of great things about the knife. Thumb stud is good, blade shape is very usable, very percise tip, and good traction plan. Some of the things I don't really like about it are the pocket clip, which rides too high in my opinion, and the coating on the blade which (as the knife ages) will wear.
My Favorite EDC

I'm a big Kershaw fan so my review might be slanted a bit. I carried one Kershaw or another for almost 20 years. By far the Blur is favorite. I purchased a second one just to pass onto my grandson. I also purchased the Purple Blur for my wife because she likes the size more than her Cryo.
Very nice

I just don't believe you will find a better knife for 60 dollars. The feel and quality of this knife is great. The assisted opening is faster than most autos. You can't go wrong buying this knife. Love it.
Great knife, but make the pocket clip for lefties
Kevin A.
Great knife, but Kershaw should make this knife so the pocket clip can be attached on the left side of the knife for lefties like me.

The handle screws go all the way through from the face of the knife, good design. Thumb studs and screws never wiggle loose no matter the times dropped. Tractech inserts never come out no matter the amount of times it gets wet or sweaty, and the best part is, though this knife is only $60 it has bronze washers for the blade to float on. They always provide a smooth and fast glide open.
