Just for the record, I'm looking closely at a hook exactly like JimWrench's item #2-down in his top pic but shorter (Pat. #672446), and the "swastika/good-luck-symbol" is very clean, crisp and as original as anything else posted here, except for Papaw's questionable example. My vote/bet goes to FAKE.
And pre-Old World invasion, North American "Indian" cultures used that design, quite possibly long before the Swiss. (My Nez Perce neighbors' ancestors were recently dated to 14,300 y/o in OR not long ago.) I've never asked what the design "means," though I do know it's meant to "impart(?)" something "positive."
HeelSpur, fakes are common and fool even museums. Read George Frank's book, "Adventures in Wood Finishing" for examples of the lengths some people go to to do just that.
