Wusthof Classic Ikon Black 4506/16 is a 6-inch utility knife manufactured in Solingen, Germany. Wusthof is a family name that’s been around for 200 years, this brand is famous for its highest quality knives and accessories such as sharpeners, cutting bases, and knife storage. I was impressed when I learned that it takes 38 steps to manufacture a single knife. Wusthof Classic Ikon Black 4506/16 belongs to premium-class chef knives. This series can boast not only an ultimately reliable blade but also gorgeous design, making it different from other Wusthof series with simpler appearance. 

I’ve created this Wusthof Classic Ikon Black 4506/16 review with professional chefs and cooking enthusiasts in mind so that they can determine whether this knife meets their requirements. Before writing this Wusthof Classic Ikon utility knife review, I tested the knife for 5 weeks, thus you can rely on my experience.       


  • Series – Classic Ikon Black
  • Type – forged
  • Blade material – chrome molybdenum vanadium steel
  • Steel grade – X50CrMoV15
  • Handle material – polyoxymethylene
  • Blade length – 6 inches (16 cm)
  • Specially designed finger guard
  • Approved by NSF, an essential U.S. hygiene and quality seal.



Wusthof Classic Ikon Black 4506/16 has conquered my heart right away when I saw it first. This is one of many reasons why I like Wusthof Classic Ikon Black 4506/16 so much. If you always pay attention to what you cut food items with, this cutlery masterpiece is totally suitable for you! Wusthof Classic Ikon Black 4506/16 looks stylish and luxurious despite its handle shells have a traditional black color. As for me, this knife is one of the best Wusthof utility knives in terms of design. Its handle looks brutal and masculine. When you only take this cutting tool in hand, you understand that it’s not just a standard utility knife, it belongs to the highest league.

Despite your kitchen design, the 4506/16 model will perfectly fit the interior and feel like an essential decor element. I find it functional and graceful at the same time. When I welcome guests in my kitchen, they always express their admiration for my Wusthof Classic Ikon Black 4506/16, especially if they are connoisseurs. Anyway, this knife always draws attention to itself with its shiny blade and luxurious, black-colored handle.    


This utility knife has a 6 inches (16 cm) long and 0.8 inches (2.03 cm) wide forged blade made of a highly alloyed single piece of chromium-molybdenum-vanadium steel. Such a composition ensures outstanding strength. The steel grade is X50CrMoV15, where:

  • X50 goes for martensitic stainless steel that includes 0.5 percent of the carbon. This chemical element turns iron into steel and ensures the blade’s strength and hardness.
  • Cr is chrome that increases metal rust resistance.
  • Mo is molybdenum, it’s a metal that increases blade’s hardness
  • V is vanadium, the chemical element that stands for hardness and increases rust resistance like chrome
  • 15 goes for 15 percent and shows the total percentage of alloying components.

The knife’s hardness is 58±1 HRC (Rockwell hardness scale), which is a quite high rate for European cutting tools. Such a hardness means that the cutting edge remains razor-sharp for a long time even if you use the knife frequently in the pro kitchen. I’ve already been using my 4506/16 model for 5 weeks for professional purposes, and it still can pass a common test with a paper. Furthermore, 58 HRC ensures straightforward manual honing and sharpening.

The knife’s ideal size and shape allow you to cut or slice fruits and vegetables, you’ll easily section pineapples and grapefruits, trim fat from meat, cut sandwiches for lunch, and do tens of other cooking tasks.  Actually, Wusthof Classic Ikon Black 4506/16 is the second most frequently used knife in my kitchen. The essential characteristic of the cutting edge is its thickness. The thin cutting edge slices thinner; however, the blade might be too fragile. This Classic Ikon boasts an optimal blade thickness. It means that slices will be thin and neat while the cutting edge is strong enough to withstand falls from the countertop.

On the left side of the blade, there is an engraved Wusthof logo, the name of the series – Classic Ikon, the model number – 4506/16, and information about the manufacturer’s location – Solingen, Germany. This engraving looks rich and respectable.    


A bolster is only a small element between a blade and a handle. However, I do believe it deserves a separate paragraph in this 6-inch Wusthof Classic Ikon utility knife review. This thickening plays a significant role in the overall knife’s construction and design. First, a bolster is a reliable finger guard – you’ll never cut your fingers instead of products. Second, it prevents food pieces from getting on the handle, making it slippy and inconvenient.

Forged knives may have a full or half bolster, and which one to choose is a matter of personal taste and habit. Wusthof Classic Ikon Black 4506/16 has a half bolster. I like it since I can use the full length of the cutting edge while slicing. Besides, a half finger guard makes manual honing an effortless process, especially if you use a whetstone. The bolster is an integral part of this forged knife, making it extremely strong. By the way, knives produced with laser cutting technology don’t have a built-in bolster, that’s why they are not as solid as forged blades.    


Wusthof Classic Ikon Black 4506/16 utility knife boasts an innovative full-tang handle, designed for user convenience and full control. Beautiful, champagne-colored grip pads are safely fastened with 3 steel rivets. However, you’ll never feel those rivets under your fingers, the surface is flat and smooth. The handle is made of special synthetic material – polyoxymethylene. It’s a premium quality plastic that provides a seamless hygienic fit, keeps its good construction and nice appearance for decades, and can resist high temperatures. On top of that, the handle is anti-slipping so that you can safely slice food items when holding the instrument in a wet hand. I’ve even tested this feature and was astonished by how reliable the grip was.

The handle is 4.7 inches (11.9 cm) long, making it ideal for a palm of any size. As I touched on above, this cutting tool looks brutal and reminds me of a hunting knife. The top part of the handle has a curved shape, which allows a reliable and comfortable grip. The knife’s weight is 0.3 lbs (133 g) which is quite heavy. You may not believe me, but you won’t notice this weight while manipulating the instrument! It is super convenient to work with! I can cut for several hours in a row without overtiring my hand. There is a steel butt or so-called counterweight with the engraved company’s logo at the end of the handle. This counterweight along with the finger guard makes the cutting tool well-balanced; it, in turn, simplifies the process of cutting and makes it less tiring.   


The Wusthof Classic Ikon Black 4506/16 utility knife costs about $100, excluding delivery costs. This price may seem too high from first sight. However, you pay for the instrument which belongs to the premium class of cutlery products and is manufactured by a reputable brand. The knife has a razor-sharp, long-lasting, and easily-restorable cutting edge, it’s convenient, durable, and reliable. More than that, it’ll add elegance and luxury to your kitchen due to its splendid design. All these factors make the 4506/16 model worth the money you pay for it. I consider it a smart investment if you live to cook and prefer doing it using rich cutlery.
