First off, the Kershaw Blur with the grey aluminum is S30V, not 440A. The black ones are 440A. I have both. I have many knives and I have always liked the Blur. When it can out in S30V, I had to have one. I carry it about 25% of the time. To me, it's a great knife in S30V and the placement and design of the thumb studs really make the Speed Safe shine.
Concerning the "pants eater" question. If you leave the clip as it is (tip down carry) it has not been a problem for me, but I wear jeans all the time. For Dockers or similar pants, it may be a problem because the material is not as tough. The bottom part of the clip rests on aluminum so that's cool. The upper portion has enough aluminum exposed so that the grip tape does not grind against the pocket top.
I perfer tip up carry and can draw this knive and open the blade in less than a second. When reversing the clip for tip up carry, the bottom part of the clip still rests on aluminum but the upper part now had the grip tap rubbing against the top of my pocket. All it took was a few minutes with a Dremel to smooth the grip tape where it touched my pocket top and the problem was solved.
The rest of the tape on the knife will rub on the inside of the pocket somewhat but unless it is your EDS 100% of the time, it is not that big of a problem, in my experience. And (this is the good part) the grip tape helps in providing a knife with an extremely good grip that will not slip, even if wet with water, oil, or blood.
