Wonder Knife - Swiss Army "Style" Knife

I don't know exactly how old this is. I can't find anything online about this particular item. We found it wrapped in the original plastic bag inside the original box. Box isn't perfect, but isn't bad either.

It was given to me by an elderly lady who we were helping move into a small condominium, downsizing. She said her late husband bought it for their teenage son probably in the '60s or '70s, but forgot about it and there it sat - in a desk drawer - until we stumbled across it cleaning everything out.
