Calphalon Classic Self-Sharpening Cutlery is peak-sharp every time you use it, thanks to ingenious SharpIN™ Technology with ceramic sharpeners built right into the knife block. Whenever you pull out a knife or place it back, the blade is sharpened at the correct angle. This 6-piece set includes a storage block with sharpeners in four slots for the straight-edge knives.

  • Built-in ceramic sharpeners automatically sharpen straight-edge knives with each use.
  • Sharp blades are fully forged from high-carbon, stain-resistant German steel.
  • Bolsters and full tangs ensure ideal balance and maximum strength.
  • Handles with three visible rivets are contoured for a secure, comfortable grip.
  • For easy identification, end caps are labeled with the knife's name and size.

6-piece set includes:

  • 3 1/2" paring knife
  • 5" santoku
  • 6" serrated utility knife
  • 8" chef's knife
  • Kitchen shears
  • 5-slot blonde rubberwood storage block.

Please note: Storage block is counted as an individual piece.

  • Made in China.
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 Love them I just bought them but so far so good I love them I especially love the self sharpening feature

    Rated 4 out of 5 by from So far so good I just received these as a gift and broke them out (and in) for Thanksgiving preparations. While new out of the box, no obvious issues and in using the utility knife for cutting up celery and onions for dressing it did a great job. Good weight (heft) and balance. Handle quality seems very good, to me that is an immediate sign of how much effort was taken by the manufacturer for comfort. I look forward to using them for years to come. FYI-I will be hand washing & drying them so I am interested to see how long the blades stay rust free.

    Rated 3 out of 5 by from I like having only the knives I need. Interesting product. I like having only the 5 knives and the self-sharping feature is the best. I would have been nice to have the care and cleaning of the knives included with the product instead of having to go to you website.

    Rated 5 out of 5 by from Always sharp!! I received the 6 piece set as a Christmas gift this past year and it has been the best gift ever! What a pleasure to use a knife that is always sharp. This set was the perfect size for me. I find I use the santoku knife the most, but the others are just as useful. I highly recommend this knife set!! You'll never regret spending the money.
