cf. Harald Dahl
“In reality this beautiful utensil is unlike anything else on the market. And the proof is in the use. Incorporating critical modifications to the ages-old fork design, the KNORK enables a user to both cut and spear food using only one utensil - and one hand.”

Roald Dahl’s dad made a knork of his own after breaking his arm, if I remember my Boy correctly. Something like he fell off the roof, and then the doctor that showed up was drunk, so instead of popping the dislocated shoulder back into place, he pulled it further out, ruining it forever.
