Skeleton knife

A skeleton knife, or cheese knife, is a type of kitchen knife that typically has three large holes on its blade. The purpose of these holes is to reduce the surface area of the blade so that sticky foods do not cling to it. Most skeleton knives are used for cutting very soft foods.

The knife was created by a Swiss restaurant and after its creating and advertisement it was stolen by many cutlery companies and private manufacturers, and is now widely manufactured from companies like Victorinox.
