Calphalon Precision SharpIN offers top culinary performance paired with ingenious self-sharpening technology. This 10-piece set includes a narrow, space-saving storage block with built-in ceramic sharpener; when you remove or replace a straight-edge knife, the blade is sharpened at the correct angle for a perfect edge every time. The set includes a carefully chosen assortment of knives for a variety of prep tasks plus four steak knives.

  • Sharp blades are fully forged from high-carbon, stain-resistant German steel.
  • Contoured, ergonomic handles are labeled for easy knife identification in the block.
  • Bolsters and full tangs ensure ideal balance and maximum strength.
  • Block and knife handles are constructed of stained maple over solid pine core.
  • Three slots in storage block have integrated ceramic sharpeners to automatically sharpen straight-edge knives: chef's, santoku, utility and paring.

10-piece set includes:

  • 4 1/2" paring knife
  • 5" santoku
  • 6" serrated utility knife
  • 8" chef's knife
  • Four 4 1/2" steak knives
  • Kitchen shears
  • 9-slot pine storage block with maple finish

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

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 Everything we need, nothing we don’t! In exchange for my honest review, I was provided this product for free. My kitchen is stocked with Calphalon products, but I’ve never tried any of their knives. Well, happy to report that it’s another terrific product from one of my favorite cookware brands! I get an excellent performance on all of the knives. I use the chef's knife the most. It has a nice weight and carves with precision. The handles are a natural grip in my hand and hold up well to daily usage. I love the self-sharpeners built right into the block. The knife block itself is very sleek, and I feel the set is reasonably priced for the exceptional quality. All of the knives were sharp out of the box, and the kitchen shears are like razors. I have been using the shears to cut my dog’s rawhides into smaller pieces and it’s so easy! This set has the essentials and is everything my family and I need. And the best part? It helps to inspire me as a cook!

    Rated 4 out of 5 by from I am picky and I'm impressed by this knife set! My son says I always complained about how dull my old knives were. And so when I was given this 10 piece knife block set to try and review, I was excited but skeptical. The built-in ceramic sharpener is such a great idea - I have never seen that before and it makes so much sense! When I say that these knives are sharp, that is no joke! I had no idea how bad my other knives were honestly until I got to use this set. Wowza. I also love that it's a space saver and fits so nicely on my counter top for easy access. I also like that they have labels on the handle so you know which knife you're pulling out to use. They feel so sturdy in your hand and that is the Calphalon quality shining through. I truly love them and because I rarely give anything 5 stars (I'm stingy that way), I'm giving it 4 stars which is awesome in my book.

    Rated 5 out of 5 by from Fast & Easy for Meal Prep My roommate and I are in love with our new Precision 10-Piece Space-Saving Self-Sharpening Knife Block Set! Since we received these knifes in exchange for our honest review, our weekly meal prep has been a breeze and quick. Each week we do lunch and dinner meal prep, which generally took forever since our old knives were very dull. But now, thanks to the self-sharpening feature our knives are always sharp. Also, living in a NYC apt, we don't have a lot of space but this knife block set fits perfectly in our counter. We'll definitely be using these knives for years.

    Rated 5 out of 5 by from Find your edge The Calphalon knives are very sharp, and they’re heavy enough to cut through fibrous vegetables with ease. The ergonomically shaped handles are comfortable to hold and are labeled for easy identification in the slender knife block. The storage block has built-in ceramic sharpeners that automatically sharpen knives with each use. The set also includes shears with a tough built-in nut cracker/ bottle opener. This set will meet all my food preparation tasks. The Calphalon knife set would be a thoughtful and useful wedding gift for newlyweds. I received this product for free in exchange for my honest review.

    Rated 5 out of 5 by from Transformed my holiday cooking experience! I received this set to review right before the holidays and got thorough use out of every knife. I didn’t need to reach for another knife once – this set has everything you need. I was very impressed with how the knife felt in my hand. The handle is nice and sturdy allowing me to effortlessly guide the blade across the cutting board with a great sense of control over my slicing, dicing and chopping. My favorite feature is without a doubt the self sharpening feature. These knives are sharp! I usually have to take my knives to get sharpened every couple of months, which is never convenient and I end up using dull knives for way too long. Excited to have one less errand to run! I’ve put off buying a knife set due to having a small New York City kitchen and didn’t want them to take up the counter space, but this set is compact and easily fits into the corner and I have plenty of counter space. Not to mention, they are a very handsome set and look great on the counter. Highly recommend this set!

    Rated 5 out of 5 by from Never a dull moment I was provided this product gratis to help facilitate my personal review. This knife set has completely changed my attitude towards prepping food for cooking. Because the three main slicing, dicing, and chopping (the chef, santoku, and pairing) knives have self-sharpeners, I know my prep is going to be easy and quick since I will not have to compensate for a dull blade. Plus, I know that the knives will still be sharp the next time I use them, no knife sharpening skills needed! I also really like how the knives feel in my hands; they have a good heft without being too heavy. My previous knife set had the same number of knives as this one (but no kitchen shears.) This knife block is less than a half-inch wider than my previous block even with the additional piece, so I did not give up any significant space to replace it. Plus the walnut block is gorgeous and looks so pretty sitting on the counter.

    Rated 5 out of 5 by from Fantastic Knives! I am in love with this knife set! I own some pretty expensive knives and have to say that I haven't touched any of them since I received my Precision 10-Piece Set. The knives are sharp, sturdy but not too heavy and, overall, really well made. But the self sharping feature is what really makes this set stand out. No more dull knives, ever! The block is stylish, sophisticated and compact, making it perfect for small kitchens or for anyone that values kitchen counter space. Also, the knives are labeled, so if you're new to the "knife world", Calphalon has got you covered and you will soon be feeling like an Iron Chef! If you're looking to purchase a new knife set for you or as a gift, I highly recommend this product. Disclosure: I received this product for free in exchange for my honest review.

  • Are these knives dishwasher safe and do they rust?

    Asked by: Suet7
    Hi Sue17, These knives are not dishwasher safe. Please see below for cleaning & care instructions: CLEANING & CARE General Cleaning & Preventing Spots and Stains Hand wash your Calphalon Precision Self-Sharpening Cutlery in warm, sudsy water using a liquid dishwashing detergent and a non-abrasive sponge or soft bristle brush. After washing, rinse and dry thoroughly with a soft cloth to prevent water spots and stains from forming. Never soak your knives in water or wash in the dishwasher. Dishwasher use will void the warranty. To clean the stainless steel faceplate on the cutlery block, wipe with a damp cloth and dry thoroughly with a soft cloth. Do not use abrasive cleaning products or scrubbing pads as these may scratch the surface of the stainless steel. Removing Spots, Stains & Water Marks The type of steel used to manufacture high-performance cutlery can be more susceptible to temporary spotting and staining. Carefully hand drying the cutlery after washing will reduce the likelihood of spots, stains and water marks from appearing on the blades; however, if you forget to hand dry immediately and spots or stains do appear, they can be removed by cleaning the blades with Bar Keeper's Friend® (a non-abrasive stainless steel polish) and a wet sponge. Rinse the cutlery well and dry them immediately before storing. Rust stains or pitting can occur when cutlery is not dried immediately after washing but is left to air dry in the sink tray or dishwasher. Pit corrosion is easy to prevent if you keep to the following rules: Clean and dry your knives immediately after use. Never put your knives in the dishwasher. Salt, humidity and heat are a disaster for your knife. Never leave your wet knife in a sink or on a work surface. Sharpen your knives from time to time to prevent pit corrosion on the cutting edge.
