I purchased this box of the attachments and it has been a hand saver and I mean that in best of terms. I had hand surgery, but need to peel a bushel of Apples to can this summer and these attachments have made it so easy to can this summer. I can wait to do the other blades, but that will be next season, since I didn't get this till I had processed the zucchini and squash this year. Thank you very much. I saw this item on "In the kitchen w/David" and had to have it.l
