Kershaw - Ken Onion - Chive  I have carried it for several years and really like it.  2" blade so legal anywhere but does most everyday job well. I don't think they make the exact one I have anymore it is black & gold with a black blade very similar to this newer one that is all black.  The assisted opening is great with a super fast dependable system.
