The Construction of a Chef's Knife

Commonly referred to as the "workhorse of the kitchen", the chef's knife is able to perform a myriad of tasks due mostly to its expert construction. The main components of the knife are the blade itself, the spine and the heel in particular, the handle, and the tang. Whether you're looking at Japanese chef  knives or knives from elsewhere, these are things they'll all have in common.

The Blade

The blade is where the magic happens, and when it comes to chef's knives, they tend to be from high-carbon stainless steel, but some fancy, artisanal knives are forged from carbon steel. The choice of material is what ensures durability of the knife, as well as resistance to staining and corrosion, and a sharp edge that can be honed to a razor-like finish.

The blades of chef's knives tend to have a tapered design - that is, a broad, curved belly that extends into a sharp and thin edge and a pointed tip.

The curvature of the blade is what allows for the signature rocking motion that's normally used with this kind of knife while cutting – this is what makes it so ideal for chopping, dicing, and slicing such a broad range of different ingredients!

The Spine and Heel

The spine is the top part of the blade of a knife (the unsharpened bit), and as you move from the blade to the spine, you'll find that there's a gradual tapering off towards the tip. This tapering is there for two main reasons.

Firstly, it significantly reduces the weight of the knife – this makes it easier to control. Secondly, it allows the knife to be a lot more precise, meaning you can use it to make delicate cuts.

The heel is found at the base of the blade (the last bit before the handle), and the purpose of the heel is to provide stability and leverage. On a chef's knife, these things are very important, and the heel of a chef's knife is designed in such a way that it can be used for tasks that require some force if necessary.

The Handle

The handle of a chef's knife can be made from several different materials, and often, they're made of a mixture of things. The materials used to make handles tend to include wood, plastic, Resin, and other composite materials (e.g. fiberglass).

Many chef's knives (especially the more high-end products) feature ergonomically designed handles for the most comfort and to ensure that your grip is secure.

The Tang

The tang of a knife is the part of the blade that extends into the handle, and it's not normally visible. When it comes to the tang of a chef's knife, there are different types - some have a partial tang and others have full tang.

The former refers to tang that extends the full length and width of the handle, while the latter includes a tang that is only in part of the handle.

Most commonly, you'll find that chef's knives are full tang because this provides the most strength and durability.

What Does a Chef's Knife Look Like?

In case you're finding it difficult to imagine what the knife looks like with all of these separate features, don't worry, because it's actually quite distinctive. It has a long, narrow blade with a curved edge, and normally, the blade's width increases (gradually) from the tip to the base, so it has a broad belly. The spine tapers down to the tip.

Chef's knives normally range from about six to 12 inches in length – on average, eight inches is the most common size for both amateurs and professionals.

Normally, you'll find that a chef's knife's shiny steel blade stands in contrast to a wooden or synthetic handle, combining functionality and elegance.

This is especially true for the best Japanese chef knives - they boast exceptional aesthetics like Damascus blades.

The nice thing about chef's knives is that they're one of the easiest to sharpen using a whetstone.
