Kershaw Tiger-Stripe Blur 1670BLKTSX Folding Knife Review

We reviewed Kershaw’s Blur Folding Knife 1670BLKST nearly a year ago and that line comes in multiple colors as well as both plain edge and a partially serrated modified drop point. Recently, however, Kershaw debuted their new Tiger-Stripe Blur (1670BLKTSX). It features the same super grip handles and the proven SpeedSafe assisted-opening system. It’s just that now, the blade bears the striking Tiger-Stripe pattern on its DLC (“Diamond-Like Carbon”) blade coating in black and grey. The DLC coating is applied using Physical Vapor Disposition (PVD), a process in which metals are instantly evaporated and ionized via a high-current, low-voltage arc and then given a negative voltage to permanently deposit a thin metal coating on the blades. The end result is a striking appearance that is extremely scratch resistant. And it really is, because we used the Kershaw Tiger-Stripe Blur knife in a ton of applications, and the finish still looks great.


And, of course, the Tiger-Stripe coating is still just the decoration that sits stop the tried and true high-performance Sandvik 14C28N stainless steel. It’s a nitrogen-rich steel that benefits from corrosion resistance as well as a 58-60 rating on the Rockwell scale. Depending upon what you consider to be the best knife sharpener (we use a Lansky knife sharpening system), you’re likely to get great results.

While we’ve already reviewed the Kershaw Blur 1670BLKST Folding Knife, we’ll still go over some of the finer points of this knife again just because it’s actually one of our favorites at the moment… For starters, the modified drop point style of this knife, while the same as in our prior review, lacks the partial serrated edge. This isn’t a pro or con – we find that users simply have their preference. The Kershaw blade has a gentle convex-curved top edge that is nice and thick – roughly an 1/8″ at the apex. As it drops down to the point, the top spine narrows and bevels along the sides create some beautiful bevels and giving the blade a truly aggressive look. There is a lot of belly on this knife, which I found to be useful when slicing open packing take and avoiding using the tip so as to not damage the contents. When sharp, the belly of the blade is a particularly useful feature.

The Kershaw Tiger-Strip Blur also uses 6061-T6 anodized aluminum for its handle. These handles are actually CNC machined with recesses so Kershaw can fill it with Trac-Tec textured hard rubber inserts. The handle is also incredibly stiff and sturdy in all the right ways. The blade has absolutely no wiggle or flexing between the sandwiched aluminum. Of course this is a SpeedSafe assisted-open blade, and the mechanism is sandwiched into the handle in a way that is remarkable. Even with the Trac-Tec and SpeedSafe, the handle is just over 7/16″ in thickness. The stainless steel liner lock was easy to use, making this a simple blade to both open and close one-handed. It’s an unusual design as well, as it nests right into the aluminum handle, rather than adding to its thickness as an entirely parallel and separate piece of spring steel.

The Kershaw Tiger-Stripe Blur pocket clip comes oriented so that the blade is tip down, but it can be reversed. It can’t, however, be moved to the other side, so south paws might find this knife to be a bit cumbersome in the hand unless you remove the clip entirely.

Kershaw Tiger-Stripe Blur Testing and Use

You cannot lose your grip on this knife. We tried the Kershaw Tiger-Stripe Blur with greasy hands, gloved hands and, of course, sweaty hands. In all cases the knife simply wouldn’t come loose – at least not through any fault of its own. This is the type of tool you can really use confidently and quickly. Whether it was sharpening carpenters pencils, or cutting through nylon rope during a recent camping trip, the blade proved to be very sharp and effective at making cuts. The blade stayed pretty sharp throughout our testing and once we finally managed to get it dull, we found that it sharpened easily and quickly back to a state where it was even better than new.



The Kershaw Blur is a great knife. It’s a solid design and has one of the most innovative and successful handle designs we’ve ever used. The Tiger-Stripe Blur (1670BLKTSX) takes a great knife and really makes it look even more impressive. This is the kind of knife that not only cuts well and feels good in the hand, it looks good from across the room. Seriously, open up this knife in front of your friends and you’ll soon have a crowd… um, for the right reasons. We have used this knife for several weeks now as our EDC (every day carry) and it just might be our new favorite.
