Before 1928, no one said something was better than sliced bread, because the bread slicer was invented in 1928. It was invented by a jeweller, Otto Rohwedder. He had been working on it for 16 years, having started in 1912. He learned that a bread slicer was doomed to fail unless it was combined with a bread packager, because when bread is sliced it dries out a lot quicker. When he asked bakers if a bread slicer was a good idea, he was told by all that it was a dumb idea. When the slicer was built, he found it very hard to get a baker to use his machine, much less buy one.
In the patent figure, 33 is a loaf of bread, and the bands 47 are like little band saws, each one slicing two cuts in the bread.
