Tomatoes are cut into equal, thin slices with a tomato slicer. He has eleven saw blades (approx. 10 cm long) in a rectangular window with a straight handle. When you place the tomato slicer on top of the tomato, you can cut it with a sawing movement. It can also be held at an angle while the tomato is pushed back and forth over the saws slightly from above (1). If necessary, there is an accompanying slide with which you can push the last piece of the tomato through the slicer, without risk to the fingers. [MOT]
