Calphalon Classic self-sharpening cutlery is peak-sharp every time you use it, thanks to ingenious SharpIN™ Technology with ceramic sharpeners for the knives 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 15-piece set includes a storage block with sharpeners in five slots.

  • 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, endcaps are labeled with the knife's name and size.

  • 3 1/2" paring knife
  • 6" utility knife
  • 6" serrated utility knife
  • 7" santoku
  • 8" chef's knife

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 3 out of 5 by from Just average I bought these knives a little over 2 years ago. Initially, one of the knives had a chipped blade. Calphalon replaced that quickly. I was impressed. Over time, I've noticed several of the knives are developing rust spots. I always hand was and dry my knives. I never put them away wet. They are ok as far as performance. Sharper than a cheap set from the big box store. I do like the built in sharpener. Overall, they are just average. I was expecting to be more impressed with Calphalon.

    Rated 2 out of 5 by from Cuts well ... really poorly made Bought this set as I've always been a big fan of Calphalon cookware. The knives are pretty sharp the sharpening is only on the larger knives. In less than a year, all my knives have some discoloration and rust. I have other brands of knives that still have no rust or discoloration on them that I've had for about 10 years. Also the scissors broke at the handle which I've had to glue back in place twice so I can still use it. I'm disappointed because of the lack of quality for being such an expensive item to buy. I was hoping this was going to be the last set of knives I buy

    Rated 5 out of 5 by from Really Sharp!!! Okay, I will say this is my first "real" cutlery set.... I have had the cheap faberware and other big box store sets.... they were awful. Tired of NOT having a set of good sharp knives I deiced to dish out the money for a decent set (this Classic Self-Sharpening 15 pc) and OMG! what a difference.... these are SUPER SHARP and holds a wonderful edge (if you take care of it...dont use on anything but food and dont "chop hard" with the blades.... you need to slice). I have had these for about 9 months and they have been great. I don't know why there are so many bad reviews.... I wonder if they are fake reviews from competitors? IF they aren't fake then these people need to use a cheap set for a while.... then they will realize this is a great set. Calphalon please ALWAYS keep an affordable set for people to make the switch and once they see how good they are, they will be back to upgrade and spend a little more. I will be buying another set and willing to jump up a little more to get an even better set.

    Rated 3 out of 5 by from Rust easily The knives themselves cut beautifully and have held up good so far but still rust even when hand washing and drying off immediately.

    Rated 1 out of 5 by from Knives go dull I've had this set about 2 years and it seems like the sharpeners in the block do more harm/dulling to the blades than actually sharpening them. I've sharpened the knives by hand to get them sufficiently sharp and within a couple of weeks of regular use and storing the knives in the block (in the "sharpening" slots) they are dull again and have little nicks in the blade edge. The knives are always handwashed and are dried/stored carefully so as not to knock into other utensils and dishes. However, it does not make a difference. At this point I'm looking at purchasing an electric knife sharpener to fully restore the knives and then buying a new wood block without these built-in sharpeners. Unfortunately, this is probably as much as a new set of knives! I'm very disappointed in this knife set as my wife and I received it for a wedding gift and hoped that it would last a long time and through many years of use. I can't believe that in 2 years I am basically considering throwing the whole set away and buying something different. All our pots/pans are Calphalon and we're quite happy with those so we expected a lot more from the cutlery.

    Rated 1 out of 5 by from Dull knives After having this set for about a year the sharpener in the block is not sharpening the knives, but rather taking small chunks out of the blade and making them dull

    Rated 5 out of 5 by from Good quality knives and a good price Just bought this set and it came with everything advertised on the box. It does have an empty slot which is actually a good thing since I plan to add a tomato knife and the extra slot is perfect. The knives seem very well made with a good balance. Smooth composite handles and good bonding with no spaces to collect debris. Unlike many cheaper knives I have tried, these seem to be made to actually use on a regular basis, not just sit on your counter and look pretty. ALL high quality knives should be hand washed to avoid rusting and pitting. Even cheap knives benefit from this. Love the self-sharpening feature. They are all very sharp out of the box. I will update this review after working with them a few more months to see how they hold an edge.
