It's hard to get IDs of tools unless it's a ratchet, socket, wrench or vise. They're what most folks use, and there's lots of them out there. These are also popular with collectors too. I've had a challenge IDing machinist tools, but admittedly these are highly specialized and doesn't seem to be much of a collector's market for them unless they're some kind of measuring tool like a caliper (though these are usually well-marked). Sometimes it's because of a tool being so obscure, who gives a hoot? There may simply be not much mechanics' interest in a mini hacksaw. Plus, it takes time to research this kind of item--someone's not likely to commit their time to such an endeavor unless they have some idea first what the ID might be (that's supposed to be your work as the owner!).
