Rated 5 out of 5 by from Best knives ! I bought this knife about 10 years ago because I was tired of the typical "block" knife sets that you sharpen more than you use. I bought this one and every time I had some spare money I would add another Henckels to my collection, I now have 6 total and never need any other knives in my kitchen. They are a superior knives and worth every penny you spend on them. I am not a professional cook but these have been money well spent. I do truly enjoy having a sharp knife when I go to grab one. Thank you for making a great product.

Rated 5 out of 5 by from Purchased this 10" Professional S knife for my husband. He's over six feet tall, and he's always complaining that the 8" chef's knife that we have is too small. He really loves how this knife fits in his hand. Nice grip and bolster that does not rub up against his finger. Longer blade makes it easy to cut and chop large quantities in a shorter time. Easy to maintain, just hone as you go, and no need to re sharpen for quite some time. Zwilling special formula steel makes all the difference in the world. Also nice purchasing a product from a company who's been around for so may decades.

Rated 5 out of 5 by from Classic German Design This is the most classic German knife design out there. Extremely well weighted, and very sharp. This knife can handle any job you need it for in the kitchen. The three-rivet handle is very comfortable, and it allows you to cut for long periods of time without getting fatigued. I highly recommend for anyone who wants a professional style knife.

Rated 5 out of 5 by from My 3rd Henckels set. I had my first set of Henckels knives back in 1986 when I was in my 3rd year in the restaurant business and learning to be a chef. I then vowed I would never go back into the culinary field because by 20 years of age, I was tired of it. I went into the infantry/artillery field in the USMC. Eventually I got out of the military and had my 2 daughters and my son in the way so I ended up falling back into the culinary world as a consultant and chef. I bought another set of Henckels... beautiful, classics. Years went by and I ended up divorced and my Henckels were gone. Now... I have started buying my set and my kids got me this for a Christmas present. I have and will always love my Henckels knives.

Rated 5 out of 5 by from Keeps Edge The Pro S is the best knife I've ever owned. The high carbon German steel is so durable, and it stays sharp for months with proper honing. I also like the full tang which adds weight as well as makes it real sturdy. The knives I've owned in the past were set at at 20 degree, where the angle on the Pro S is slightly smaller, making it much sharper than other knives. I also like the fact that it is dishwasher safe, just in case one of my kids should put it in the dishwasher! The lifetime warranty gives me the security I needed to make this purchase, and I am so glad I did.

Rated 4 out of 5 by from TRADITIONAL + Perfect balance, very durable. Purchased this knife for immediate relatives in need a a great knife. Being so sharp I love how it has the full bolster which acts as a guard. Has all the traditional features needed in a chefs knife however Zwilling's special formula steel makes a difference in performance/durability.

I’m new at purchasing quality knives and trying to figure out which is your top of the line Pro or Pro S? Also looking at sets you don’t specify what size they are?? (3 pieces) A chart of some sort would be helpful.

Why does the description say Item # 31021-203 and on the knife in the picture it says Item # 31021-200? What's the difference? If I order this what will I get?

Asked by: LelaniaM
31021-203 is a newer SKU for the same item. Item numbers change for various reasons, but the product will remain the same.

What's the difference between "Pro" and "Pro S" models, across the range? There seems to be no difference based on descriptions, and/or price. Thanks

Asked by: WiscoSkip
These two lines are materially the same. They differ slightly cosmetically; the Pro bolster has a half arch design while there is a full bolster on our Pro "S" knives.
