if you are near a polish or german community, cabbage slicers like you post were pretty standard, though nowadays most people use machines. as a kid i had crocks of kraut all around the place. as you said, you have to be careful or you bleed... a lot.
i just use a heavy duty cuisinart food processor to slice up cabbage. works well, quick, and easy (and I haven't found a way to cut myself with one yet).
