And it's the SOG Blink! I've been using one for a while now and like it a lot. I keep it in my back pocket and don't even know it's there, usually I cannot tolerate anything in back pocket.
Very thin, about the same length as a folded bill, wide and sturdy clip that will hold bills in place, and even a safety if you are paranoid about the blade opens in pocket. The scales are hard anodized aluminum, provides enough traction to hold things in place without being too grippy.
A few photos:
Good shape, square-ish, works well for the purpose.
Nice blade shape.
Look how thin the handle is.
Showing off my riches with $5 bill.
Well hidden behind folded bills.
