I know Case made one of these. considering this seller's history of questionable knives I wonder is there any chance this is authentic. It maybe an original Case blade put into this frame. I'm pretty sure I have one in my junk pile that has been made the same way. Also found something on the net I'll include about the Case wire jack.https://www.ebay.com/itm/VINTAGE1920-TO ... 0290.m3507
The Case Cutlery Company also sold a "Wire Jack" pattern knife (W1216) using a couple of variations on their tang stamps e.g. "CASE TESTED XX" and "CASE PAT. 9-21-26". In both of these stamps, the word "CASE" is the older "tested" 1920-1940 version. The stamp could appear either above or below the cap lifter. These "Case" knives were made entirely in the Schrade company in Bridgeport, Ct. This was common for one knife company to make knives for another, incidentally, Schrade also made "Pull Balls" for Case and large switchblades for Remington.
