Westhof is a very reputable brand in the kitchen utensils space, with most of it’s products known for their quality and longevity.

The 8-inch Classic Chef’s Knife is a staple within the Wusthof range, specifically for chopping, slicing and dicing for vegetables (or onions in our case).

As you can guess, it comprises an 8-inch blade with a 4.5 inch (ca. 11 cm) handle that sits snugly within your grip.  Wusthof boast an ergonomic design, to ensure comfort and safety while you are using the knife.

The handle not only looks fantastic, but it is also designed with safety in mind.  The closer grip design ensures knuckles are neatly tucked away and is meant to encourage the professional rocking style motion of cutting.

The prized feature of the Damascus Knife is the metal of the 6 inch blade.  It is 67 layers of of damascus steel with a 60-62 hardness level.  It has also undergone deep vacuum cooling which provides the blade with corrosion resistant properties.

Buyers Guide for Buying the Best Knife for You

In this section we are going to look at the features of a knife that will make the difference between a good knife and a great knife.

Material and Construction

If you are going to buy the best knives, you should look for ones that are made from single pieces of metal (including the handle).  Being made from a single piece of metal provides the knife with durability and strength.  This results in fewer breakages and a knife that will last a lot longer than other inferior knives.

You will notice a trend that many of the best knives are made from varieties of stainless steel or high carbon stainless steel.  This is because stainless steel possesses anti-corrosive and anti-staining properties, making it ideal for crafting knives.  In addition, stainless steel is a strong metal that can retain a sharp edge for years if maintained and cared for appropriately.


You may think the main thing to consider when purchasing a knife is how sharp the blade is.  However, the handle on a knife is just as important as the blade.  Without a well-designed handle, a knife would be next to useless.

For a handle to be effective, it should be ergonomically designed and sit comfortably in your hand.  You should not need to grip the knife with a strong grip, otherwise the knife could slip out of your hand and potentially injure yourself or other people.

In addition to the comfort factor, there should also be a distinct presence of non-slip features such as bumps or grooves on the knife’s handle for grip.  These features are there for safety and are generally included on the best knives available.

Balance and Safety

Only the best knives are well-balanced.

The balance of a knife is important because it aids in the natural cutting motion.  When you use a balanced knife, you do not require much force to cut through the toughest of foods and materials.

To tell if a knife is well-balanced, simply place the knife on the tip of your finger at the point where the handle meets the blade, it should sit perfectly balanced.

The balance of a knife becomes important when it is being used.  If a knife is not well-balanced, it will be difficult to use and may force an individual to hold or use the knife inappropriately.  This can lead to safety issues and potentially end in injuries.
