Strange new knife........

[knife7knut]

Picked this up on e-Bay recently just because I love unusual knives.Made from 1/4" stock the blade has three concave grinds along the blade.Tip is a screwdriver with a built-in cap lifter.Asymmetrical 3/16th inch thick brass guard is well fitted.Handles are of some synthetic(does not polish up and is warm to the touch);possibly polypropylene(doesn't give off an odor when rubbed)held by two large brass rivets and inlaid with small pieces of brass wire in a pinwheel form.Ends of grinds are a bit crude but the grinds are straight and blade is relatively wave-free.Balance feels pretty good as well.
No maker's name.
Anyone ever seen anything like this before?Any info greatly appreciated.
