Frederick Hoelzel's Cutlery

Origin
Frederick Hoelzel started eating unusual objects as a teenager to lose weight. His meals included corncobs, crayons, sawdust and surgical cotton, among other normally indigestible materials. When he attended the University of Chicago, he used his skill to measure the amount of time it took inert materials to travel through the digestive tract. He swallowed gravel, gold pellets, wiring and glass beads. His extreme diet ended up leaving him skeletally thin.

Effects
Anything consumed with these utensils can pass through the human body with no adverse reactions. Extended use will emaciate the body, however.
