Looking for an EDC pocket knife. Little bit on the inexpensive side.?

Im looking for a new EDC knife. I currently have Kershaw Ram and Love it but its big, heavy, and scary.

My requirements, not in any order.
-Cost $50 or less but I am flexible if I can get an amazing knife for $60
-Blade size 3″ or smaller (still flexible but I want a smaller lighter knife)
-Not scary, What i mean is something I can pull out say in public to open my bag of skittles and people wont get uneasy around it (seen that happen with tactical styled knives)
-Pocket clip is a 100% must have
-Decent blade steel, nothing with steel such as AUS4
-Some kind of locking mechanism
-The ability to open one handed, wether it be a thumb stud on the blade, a flipper blade, or a spring assited blade theres times when one handed opening is a must for me.

Heres what ive looked at but Cant decide and im still looking for other thoughts.

Guess I might add NO SERRATION. Cant stand serration and my knives are kept sharp enough that its not needed Maybe on a survival knive but for EDC if my knife cant cut it its either A: Not being maintained in the sharpness department B: wrong tool for the job
