I don't have one of those but I have one that's very similar. It belonged to my wife's grandfather, who was an engineer officer in WWI (US Army). The biggest difference is that it doesn't have those odd serrations. It's also not stainless. An almost identical one is still manufactured.
I also have a ton of old tools that once belong to him, too. More cutting tools than I've ever had. Haven't used a single one yet, except for the heavy-duty crosscut saw, which I think I mentioned here somewhere before.
