Oddity found in my basement

[Pheasant Hunter]

Well, I bought my home 4 years ago. To be honest, I've never thoroughly gone through the stuff that was left in nooks and crannies in my basement and attic. This was tucked away on a shelf in my basement...
It's "MACK-THE-KNIFE by Henniker's"
"Crowning Achievement of Cutler's Art"
"Crafted of hollow-ground stainless steel and rosewood, most versatile knife ever. Use as Slicer - Chopper - Carver - Parer - Bottle Cap Lifter - Fish Scaler - Can Opener - Frog Holder Downer - From-the-Jar Pickle Snatcher... and much more."

This knife is still in the original box with the blade cover and appears unused. I tried looking it up on the internet, but no info seems to exist. The end of the box says, "Stainless Steel Japan." Anyone know anything about it? I'm interested in learning more about my strange find.
