I think Tekna maybe (Techna)? made one. I got one for my dad years ago. He loved it. It was credit card shaped and a wide flat double edge blade slid out the end. When he died my scumbag nephew swiped it and sold it for dope. They made a lot of flashlights. My dad did things with that knife that it probably shouldn't have been capable of. It was in fact his EDC. I never knew him to carry a conventional pocket knife but he carried that crazy thing. He sharpened pencils with it, opened boxes, cut string, whittled a very little bit on carpentry projects...regular light duty EDC stuff. He loved that thing.
