All About Pocket Knives

Could someone help me get information on a knife that my son gave me for my birthday. It is a 2 blade stag knife, one blade is clip and the other is a saw blade. The tang has the marking of { MANZ } I have taken it to a knife show, there was a lot of interest, but no one had any ideas! Any help would be appreciated.

Please find two attached files that contain photos.

Welcome to AAPK.

I checked Levine's Guide to Knives & Their Values and did not find this manufacturer listed. Others will probably post who have more info than I do.
Looks like a nice knife. I'd bet it's circa 1900's or even earlier, probably European (maybe German?)

Goins doesn't list any Manz either. but it looks like an old German made knife to me? Terry
