The Knork (pronounced "nork") is a utensil which, like the infamous spork, combines two of the three most common eating utensils into a single unit. In this case, it is a fork with rounded, wide edges which can be used to safely cut food like a knife, without a sharp edge to cut the mouth of the user.
Ergo the name, a fusion of knife and fork.
This utensil was invented by Mike Miller, now-owner of Phantom Enterprises, a company set up to produce and market his invention.
In some sense, a pastry fork is a kind of knork (and/or a precursor thereof), since it is also a fork designed to be used as a knife for cutting the food.
Unlike the spork, which gained fame through KFC as a cheap, disposable alternative to real utensils, the knork has been marketed as a high-end utensil, costing almost five dollars for a single unit.
