Cheese Slicer

The cheese-slicer is a Norwegian invention. It is a hot summer day in 1927  and Thor Bjørklund is having four slices of bread with "gouda-cheese" at his lunch break in his carpenter-workshop at Lillehammer. The heat of the sun has caused his cheese to melt and look uninviting. So he tries to divide the slices of cheese with his carpenter’s plane so that he doesn't have to eat so much of it. It is a bit unwieldy for cutting cheese so he decides to make it smaller. After thinking about this over night, he finds a thin slice of steel. He trims it and bends it down, while the back of the steel-slice is bent up. It proves a success so he takes out a patent.
