The Blur is a great everyday carry knife. It sits nicely in the pocket next to your wallet and doesn't shift positions. The shape of the handle fits perfectly into the palm of my hand and affords a very secure grip. The knife can be opened by applying medium pressure to the thumb studs to flip open with an assist with either the left or right hand, with a satisfying snick. It can also be opened manually with two hands. If you don't apply enough pressure with your off-hand, it might not open fully, but a simple wrist flick will lock it into place. It can't be flicked open when it is fully closed.

The knife performs very well under heavy use. The knife tip easily pierced and pried away a beer bottle top allowing a quick mid-turkey day beer as I was preparing our Thanksgiving feast. I also used the knife to open a can of sardines with ease. The knife penetrated the can like butter. It handled these light metal items without breaking, scratching, or chipping.

Other kitchen chores, such as peeling/slicing fruit and veggies were handled with ease. The Trac-Tec inserts provided a very secure grip, even when my hands became wet and slippery. The Blur made quick work of preparing a turkey for the oven. It sliced through thick sections of extra fat, skin and grizzle with ease. The tip aided butchering greatly. A large neck bone was sliced through with some heavy careful pressure...I was afraid that the knife would pierce through the kitchen sink!

Cleanup was straightforward and simple. Soap and water quickly cleaned the interior surfaces and no chicken was left on the blade or mechanism to my eye or nose.

A note on blade geometry:

From the side, you'll notice that the knife edge is recurved. Blade thickness increases as you approach the spine, where it meets a ridge, and then thins out a little, providing a false edge look. The ridge itself is a long triangle with a curved hypotenuse, that extends back down to the blade below the thumbstud. This provides a half groove like shape which makes slicing or pushing through objects easier, since it won't stick to the blade.

The spine is 1/8" at the base, and tapers ever so slightly to the point.

The unusual blade shape means that it leaves a slightly triangular shaped "wound channel" when stabbed and a slightly curved cut when drawn through material. This makes quick work of cardboard and other hard cutting tasks. However, this also means that means that highly presentable food preparation is out since surface edges appear slightly curved. It's fine for my kitchen table though.

I compared this to two other knives I own, a CRT M-16 in AUS 6 and a composite Kershaw Shallot in ZDP-189. It is immediately apparent why I preferred using the Shallot for cutting and dicing, since it is a thinner blade.

But you will also notice the shapes of the spines that give these knives their strength. The base of the Shallot is doesn't start to narrow until a little more than a third of the way up the spine. The Blur's 1/8th" thick spine narrows a fifth of the way up of the blade, but narrows only slightly, lending it great strength and flexibility.

You can also see why the Blur is much easier to clean than the other two knives from this angle. Lots of space for water to wash through the knife and away from the assist mechanism.

I'm excited to take this knife into the outdoors...it has all the properties that a camping/fishing/hunting/survival knife should have.

Nice review :thumbup:. Add some pics and it'll be gold (hint hint). :D

It will be interesting to see how the assisted mechanism holds up to dirt/fish guts/etc. in an outdoors role. Looking forward to hearing about it!
 
Great review and nice pics. I liked your comments on using a recurve for food preparation. I have used a ZT301, which has a recurved blade for some food prep while camping and while it might be bombproof in the field it isn't great in the kitchen. I really like the flipper for deployment but it makes it less usable on a cutting board. The Blur seems to have a nice continuous line of uninterrupted handle and blade, which you show, make it very handy in a kitchen.

I think your inclusion of how easy the knife was to clean-up is great information. Your review is helping me approach, more formally, the ways in which the aspects of knife design impact it's use on a daily basis. Which knife meets your needs, and appeals to you depends entirely on your use case. Thanks for being a good sport and I hope you had as good a Thanksgiving as I did :)
 
I have had the tanto blur for almost three years... LOVE IT... it hasnt left my pocket since the day I bought it... Great edge.. Great edc choice... Opens with authority... love the knife one of my favorites... Recently the speedsafe broke in the knife but kershaw customer support sent me out new parts and a tool to fix the knife... so no worries. I have used this knife to cut just about anything you could imagine and it still looks beautiful. I would recommend this knife to any new or old user.
 
I have maintained the factory edge on my blur since I got it. I find the factory edge to be perfect. I maintain all my knives free hand on a wet rock, and with the factory edge its pretty easy to bring it back whenever it dulls a bit. Then a few strops on a leather belt and you can shave your face.
 
Thanks for sharing too.

The only reason I didn't get one years ago (got an Endura instead) was because of the liner lock. If the customizing done by STR here for them is any indication, a framelock version I think it might sell very well.
 
I havent had any lock up issues with my blur. It locks up like a jail house. (yes i understand the liner lock on the blur is not as strong as other offerings.) untamed I recently bought an endura 4 emerson wave. Love the blade and it its a stronger more "tactical" blade than the blur.
 
ubuwalker,

Excellent review and thanks.

What I like most about the Blur is the shape and aesthetics of the blade.

What I like least is the assisted opening. I don't want or need it, and it can seem somewhat threatening to the uninitiated.

I had the torsion bar removed on my S30V Blur.

Now it opens like any other manual knife, using the wonderful thumb studs with jimping. (These may be a bit sharp for pocket EDCing, IMO.)

As others have noted, the linerlock seems thin for a knife of this size. That said, I haven't noticed any problems in use.

My knife is new and the clip is still too tight for easy pocket use.

One other thing: Kershaw says that the blade on its S30V model, unlike its cheaper Blurs, isn't coated for corrosion protection. A puzzling oversight, I'd say.

S30V has a good deal of corrosion protection just from its makeup and the blade is a smooth-stonewashed finish so it's going to be hard for corrosion to take a hold on the blade. Some people don't like coated blades, and the stonewash finish is for the user who doesn't like to see scratches on his/her EDC. :thumbup:

A good observation and thanks. To my knowledge, my two S30V mini Ritters also are stonewashed and uncoated.
