That could be the same reason my Dad bought this one. I have no idea what he paid for it. Maybe a dollar or two. You could buy a good Case knife for about $6 at that time. It seems to me that Guttman had a cutlery factory in Germany and they also sold other types of knives. Edgemark? That seems like the name they used here. It seems strange to me that the Mitsubishi trademark is only on the case. Is yours marked that way too? Best wishes IMR
