Different Types of Kitchen Knives

How many kitchen knives do I need?

This is all down to your personal needs and preferences. If you are building your kit from scratch, start with a chef's knife, a paring knife and a bread knife. From there you can build your knife collection based on what you use, and what you cook in your kitchen. You might want to add a couple of different sized chef’s knives. Or complement with a Santoku for a different shape. You might love using your paring knife and want more of the same, or a couple of different sizes. Or adding a filleting knife if you eat and cook a lot of fish.

The Anatomy of a Kitchen Knife

What are material hardness and sharpening angles?

Material Hardness

The hardness of the steel of a knife is measured in something called the Rockwell scale, shortened to HRC. Knives generally range from about 52 to 58, with some very premium knives going as high as 64. The higher the number the harder the steel. A harder steel will keep a sharp edge for longer, however, on the flip side, it will be more work when you sharpen it to get the edge back. Whereas a softer steel needs to be sharpened more often, but it will be very easy to get that sharp edge back.

Sharpening Angles

You tend to get two options for the angle the blade is sharpened to. Western style knives have previously been sharpened to about a 22 degree angle, and Eastern knives to about 15-16 degrees. Although you will likely find that many knives, both Western and Eastern style knives are often sharpened to about a 15 degree angle nowadays.
The finer angle of an Eastern style knife is because of the cuisine that is often cooked in that area of the world. Softer vegetables and meats. And in the western world people often eat more root vegetables and tougher meats, and you may need to cut through bones. So a slightly wider angle will make the knife more robust and suitable to the cuisine in that area of the world.

Common Kitchen Knife Blade Materials

Stainless Steel

Stainless steel is the most common material that you will see in a kitchen knife. This is because it is one of the more affordable options. It is a durable, rust and stain-resistant material that is easy to sharpen but since it isn't as hard as damascus steel you may need to sharpen it more regularly.

Damascus Steel

Damascus steel has quickly become popular over the last couple of years, it's made by folding two types of metal together which is also what creates the classic patterns you can see on the blade. Most commonly they have a carbon steel core with layer of stainless steel outside. They are easily identifiable by their patterned appearance which happens during the forging process. They are both tough, durable, resistant to wear and able to sharpen to a fine edge - which is what makes this material just so popular.

Carbon Steel

Carbon steel knives are a little more rare and require different treatment to other metal blades. They are a type of stainless steel that is more susceptible to rust but, they are also easier to sharpen. You need to keep the knife dry and regularly....

Ceramic

Perhaps now a little old-fashioned you do occasionally see a ceramic knife. Compared to other materials they are much more lightweight yet can be sharpened to a fine edge. However they are more brittle and prone to chipping if used incorrectly or sharpened without the proper ceramic tools.

Forged, stamped or cut - which production method is best?

Stamped or cut knives are stamped or laser cut out from a sheet of metal, and after that shaped and sharpened to get your desired finished product. Stamped or cut knives are generally lighter than a forged knife. Forged knives are forged/hammered into shape from a solid piece of metal. The metal is heated up, and then forged and shaped, before it is sharpened. Forged knives are often heavier, and tend to have a full or partial tang.

The process of making a forged knife is more time consuming and labour intensive. So forged knives tend to have a higher price ticket than a stamped knife. Although with todays technology, a stamped knife doesn't mean bad quality, there are a lot of other factors to think of when buying your knife. And the most important thing is that you get a knife that works well for you.

Common Kitchen Knife Handle Materials

Wood

Wood is the material most commonly used to make knife handles - specifically hardwood. This is because it is naturally non-slip, warm and comfortable to the touch and aesthetically pleasing. It also gives the knife a good balance which is why it is many professional chefs first choice. It does, however, require more up keep and regular oiling.

Plastic

Knives with plastic handles are most commonly found in commercial kitchens because they are the easiest to clean, most non-slip and therefore the safest and most sanitary. This may also be the case because they tend to be cheaper. However, plastic handles also tend to be the most uncomfortable to hold and use.

Composite

Composite handles are often made of a mixture of resin and wood, so you get the wood affect without the maintenance. A common example to look out for is Pakkawood, which is made from layers of hardwood veneer which is then compressed at high temperatures and pressures before being impregnated with resin. The resin makes the handle waterproof and resistant to heat or temperature changes.

Metal

Metal is a more uncommon choice of material for a knife handle, however it is a very durable option. It requires no upkeep other than regular washing - plus they tend to be produced from one piece of metal which means they are virtually impossible to break. Although it should be noted that these knives can be more dangerous as they are slippier if the handle gets wet or oily.

Glossary of terms

Butt: The back end of the knife’s handle, see our infographic above.

Full-tang: when the tang extends all the way to the end of the handle

Granton edge or scalloped edge: This refers to the chopping edge of the knife that has curved circles. It stops a vaccuum from being created when chopping food so it can more easily slide off the knife.

Half-tang: when the tang extends part way through the handle but not to the end

HRC: Refers to the hardness of the knife on the Rockwell scale. See above on material hardness for more info.

Rivet: The metal circles you see on western style knives. They secure the tang to the handle.

Serrated edge: A serrated edge is what you will most commonly see on a bread knife. It helps to slice through surfaces that are tougher.

Spine: The part of the blade that is opposite the edge. It is the thickest part of the blade. It can be used to apply pressure when using certain cutting techniques.

Tang: The part that extends from the blade into the handle.

What is the difference between a chef’s knife and a santoku knife?

Santoku has a more straight/flat blade than a chef’s/gyuto knife which allows for a more up and down cutting motion, rather than the rocking motion we may be most used to here in Europe. It will do all the same things as a chef’s knife, and it’s your preference which shape you like best. Santokus tend to have shorter blades than the average chef’s knife. You will generally not find a Santoku with a blade longer than 18cm.
