KershawBlur Blackwash Folding Knife (1670BW); 3.4 BlackWash 14C28N Steel Blade; Black Anodized Aluminum Handle with Black Textured Trac-Tec Inserts, SpeedSafe Opening, Reversible Pocketclip; 3.9 OZ

Probably the absolute best Kershaw knife I have owned yet. The speed-safe mechanism is fantastic on this knife. Works much better than the cheaper Volt II and the Tremor I have owned. The scales are very grippy, and the blade stays sharp forever.I just wish the pocket clip was a little deeper riding, like the clip on the Cryo. That is the only complaint I have about it, because all replacement clips I have found are pretty expensive.Edit - Update: Feb 2025I still have this knife.Honestly, it's one of the best knives I've carried on a daily basis, and one of the few that I have that I can easily say that I'd replace in a heartbeat. I absolutely love this knife and how it feels in my hand. The blade is incredible, and will cut whatever you need all day long. Obviously, with the thinness of the blade and the geometry, it's not meant to be hammered through stuff, not would I with any frame lock knife - which brings me to my only dislike about this knife. I know it's just me being picky, but I do wish this had a better locking system. I know it'd be hard to implement, and honestly I'd be worried that it would destroy a nearly perfect knife design.Ken Onion did a fantastic job designing this knife, I've bought many more knives since I purchased this one, but it's been nearly impossible to find a folding knife that fits my hand as good as this one does. Congradulations Ken, you've ruined me forever in trying to find a knife I like as much as this one with a better lock. I'm not joking, thats my general criteria now when I'm looking at a new folding knife, find one that feels as good in the hand as the Blur, with a better locking mechanism. And I'm having a terrible time doing so. Almost no one out there seems to know how to make a truely ergenomic knife handle.I will continue to carry this knife once in a while, as I feed my addiction of obtaining sharp pointy pieces of steel.

I already own several Kershaw Blurs and decided to purchase this one because I wanted to add a Blackwash version to my collection. I really like the Kershaw Blur in all its varieties. I personally think you get a lot of knife for the money spent. It feels great in the hand, the blade material 14C28N Sandvik Steel with Blackwash finish is superb! Handle is made of anodized aluminum and has Trac- Tec inserts that provide for a good grip on the knife. The assisted opening of the blade is smooth and quick that it actually is ironic that the knife is called the BLUR since the opening of the blade is like a blur before your eyes. Reversible pocket clip tip up or tip down. Kershaw Speedsafe USA printed on the handle. Pocket clip has Kershaw engraved on it and the clip has a Blackwash finish. Ambidextrous thumbstuds on the blade with the model # 1670BW KAI Patented Ken Onion Design printed on the blade. There is some jimping at the back spine of the blade and also on the handle on both sides that correspond to where the jimping is on the blade. Like I said, you get a lot of knife with a lot of detail and great quality for an affordable price. A great collectors knife for the modest income knife collector or just a great EDC knife for anyone looking for an EDC.

I use this knife at work. I cut plastic wrap, plastic strapping, and heavy duty cardboard boxes, rated at 265 poundsOut of the box impression was high. The blade was shaving sharp upon opening. The finish is very nice. It’s feels very solid, and opens with authority. It feels very good in the hand, not too heavy, but not too light. It is also the perfect size for medium duty cutting.The razor sharpness lasted a day at work, but was still plenty sharp enough to easily slice through boxes. I generally don’t sharpen the first couple of weeks, just to test edge retention. After three weeks, I could feel the blade catching, but still slicing through the boxes fairly well.Sharpening with rods brought back the paper cutting edge, and a strop made is shaving sharpe again.The ergonomics of this blade will keep it in the “grab first” pile. The ease of sharpening the blade vs the edge retentions will keep this knife as a daily front runner.I bought this blade as the s30v blade first, but I feel this steel is easier to sharpen than the more expensive blade.

Solid performance for a good price.Pros:Price, weight, size, looks (blackwash looks cool), easy EDC knife choice. Opens and locks securely. Fit and finish good. USA made.Design is robust enough for actual use. So far have cut branches, small saplings blocking trail, ranging from 1/4" to 1/2" in diameter quickly without issue, opened cardboard boxes, padded envelopes, cut food including hard salami among other daily tasks and the Kershaw Blur BW handled them all without protest. Survived a drop onto rock with only a few minor scratches to the handle, (didn't take due care to ensure the clip is fully engaged when returning it to my pocket), so now it has 'character.'Easy to sharpen. After some abuse cutting small saplings, a couple of swipes with a ceramic 'steel' smoothed the edge out nicely.Minor Cons:Dull as dirt when arrived; so much for Kershaw's rep for shipping sharp knives, by this example. Might have been missed by factory QC. May have a different idea of useful sharpness. Didn't take too long to get it useable with a stone. This my first Kershaw and not a big deal, IMO.Opening action very, very tight when rec'd and prone to hanging up. Lubed it and played with it and by the following evening was opening without a hitch.All in all, a good, quality, useful knife that should perform well for years.

Great all around knife. Tight, sharp, great opening snap. My only complaint is the pocket clip… it sucks. I had to purchase a Lynch deep pocket clip. Kershaw should ask their partners at Zero Tolerance about making decent deep pocket clips. Other than that it’s a great knife.
