Well, I never read the fine print/patent descriptions on these things, too convoluted and I start getting migraines. I personally think its a well thought out design, however, I would have made the tooth extraction hook on the handle end in a different fashion. Personal preferance. Nothing like an impacted tooth out on the range. I agree, the hinged spork must have been a game changer for it's time and probably propelled our friend Loudon to infamy. I am getting called to supper (it's frog leg night) so I will continue later...
