Marv's link is the Swiss Army Knife of web pages, about longest sellers pitch I can recall. But halfway through No. 14 is identified 'Multi-purpose Hook (parcel carrier)'. Old fan of Swiss Army/ Victorinox products, seemingly far back as I can recall.
Pure entertainment, scan over the 'SwissChamp' model; everything but diesel generator and landing gear.......

I also have older J. Rodgers cutlery from England, terrific as well, but no parcel hook. Or corkscrew!
