I like the blur and have a couple of them, they are very comfortable to use, carry, and deploy, they also cut well.
However, the pocket clip is awful, it’s not offset enough from the handle to have enough clearance for the thicker seams on my work jeans, and it sits too high in tip up configuration, I’m not a fan of low rider clips in general, but kershaw should have updated this clip by now or offer a variation that sits better in tip up.
The other gripe I have is that recurve, it cuts so well, but doesn’t resharpen well on a flat stone without rounding the shoulder of the stone. Touch ups aren’t a problem with sharp maker or just a ceramic stick, but heavier work is made much harder due to that recurve.
Some of the blade variations don’t have the recurve while most do, most are hollow ground and a few are flat or mostly flat ground. The hollow ground versions are quite thin behind the edge and slice well, but the flatter ground blades like the S30V is quite a bit thicker and aren’t as slicey.
My favorite was the SG2 blur with dark brown handles, it was so thin and sliced extremely well, but sadly I sold or traded it years ago.
