How much food is wasted?
Usually just a little, about inch. If I am making French fries then I will just slice the remaining piece with a knife before I put the fry in water. The tomato is not a problem because you do not want the top anyways. Other foods you will have waste because ultimately you would rather have wasted food than a sliced finger. And for the record, both my wife and I have cut our fingers on this unit. Not a tool I would let a young child use, even if supervised and using the food holder. Food I have used Potato- This is what I use it for the most. I can make shoestring fries or fast food size fries with this machine. It works very well for this as long as you keep up the force when sliding it across the blade. I just wish they had and adjustment for homestyle fries. Cabbage- You have to first cut the cabbage into smaller pieces. Then you are going to get a combination of strips and pieces. Then if you want coleslaw (which I wanted) then you have to further dice it. I did not feel it helped
