Offering a great variety of knives and sizes, the 20-piece set includes a storage block with built-in ceramic sharpeners in seven of the slots.

Use & Care


  • Always use caution when handling sharp objects.
  • Avoid cutting on hard surfaces such as stone, metal or glass.
  • It is not advisable to use any knife but a meat cleaver to cut through bone, as other blades can be easily damaged.


  • Hand-wash with warm water and a mild detergent; rinse and dry immediately.
  • Avoid cleaners containing bleach or citrus extracts.
  • Storage slots with an integrated sharpener automatically sharpen straight-edge blades every time you remove or return knives to the block. There is no need to bear down or apply excessive pressure; the sharpener is designed to work efficiently with your natural motion.
  • Do not place serrated-edge knives in the sharpening slots. Sharpen serrated knives at home using a sharpener specifically designed for a serrated blade, or have them sharpened by a professional.

    Rated 5 out of 5 by from Amazing set of knives My husband bought me this set last weekend and they were invaluable for preparing Easter dinner. I love the weight of these knives and the feel of the handles! This set has every blade i could ask for and man are these blades sharp.

    Rated 1 out of 5 by from Rust! Bought these knives after rave reviews only to have them rust the first week! We hand wash the larger knives and dish wash the steak knives. All showed significant rust. Also, the dark block shows every small spot and scratch too well to have out on display. I thought the labeled knives would be helpful, it just looks cheap. I did tons of research prior to my purchase for this somewhat basic set and so upset I had to return them because it truly should have been a good set. Oh well.

    Rated 5 out of 5 by from What a difference!! I bought this around the beginning of the year, and they have made much kitchen work a joy instead of a chore. (I guess my previous motley collection was pretty much a disgrace!) LOVE the self-sharpening feature. The knives are well balanced and easy to use. Having the names of the knives on the ends of the handles eliminates some aggravation -- a lot of visitors who notice that comment on how much they like that feature. Go for it!
