I had that same Kershaw blur, and after spending over $100 on it I never liked it. The thumb did was to close to the handle for me. I bought the CRKT no time off and really like it $130.

Is that what it's called a blur??? I've owned two so far can see the date on this ones blade. Broke the first one upside down in a overturned semi tractor trailer cutting the seat belt of the restrained driver to free him. I think I hit tip on hinge of the seat and that's what broke it never did figure it out. But I called them told them what happened and they replaced it for free so I have no complaints on it.
