I use my mandoline every day during the summer for cucumbers, I believe it is a OXO. While I LOVE
it; for cabbage, I do what Joe suggested w/ the processor. If you do not own one, I am still not sure I would recommend your first attempt at using a mandoline to be with a hard cabbage. Be careful, they are really sharp. I know a few friends that cut themselves with use as well as cleaning. (Hubby was not prepared for the blade)...
Good luck and have fun! You can do so many things with them! Joe's video does a nice job demonstrating how to use, if you need help, reach out!
