It's from Duluth Trading Co. It's their brand I guess. I think it is actually the tiny, or maybe they called it micro, I can't recall. I like a knife that fits in the coin pocket of my jeans.
It's a higo, from Japan. Got it from Duluth trading co. No, it does not lock open. You hold it open with your thumb by pressing down on the lever. Worth note, it's not stainless, it's forged carbon steel. If it's put away even a little wet it will rust.
