What kind of knife do you use regularly?

 

Whether it’s for your family or yourself, kitchen tools are crucial for people who are cooking every day. If it’s possible, you want to be able to use your kitchen tools for a long time, right? Although there’s also a lot of people who think that they “somehow will use the kitchen tools they choose for a long time.”

 

I, as a housewife, am also that kind of person. So, to focus on one thing, I think we should know about kitchen knives first.

 
 

 

To begin with, I will introduce the type of kitchen knife. In addition, there’s also a thorough comparison up to the difference of the materials and styles.

 

Various kinds of kitchen knives are made according to their purpose and food materials. The kitchen knives’ world is intense.

Various kind of Kitchen Knife

There are a wide-ranging variety of kitchen knives. Kitchen knives’ types are categorized according to the function of cutting certain types of food material. Still, due to the difference in structure, they can be roughly divided into two types, which are “Western knife” and “Japanese knife”.

Western Knife

It’s a general term for kitchen knives used mainly in Western cuisine.
Initially, it was made to cut meat, and it has developed mainly in Europe and the United States.

Structure/How to Cut

Youbouchou (Western knife) is a V-shaped and “double-edged” structure with an asymmetrical blade cross-section.

 

The primary purpose of this knife is pressing and cutting (push-cutting), using the weight of the kitchen knife, while pushing the knife forward, cut by applying force from the cutting edge towards the blades. Cutting in this way makes it easy to cut even solid or hard food materials.

 

Because this “push-cutting” technique can apply strong force, it is suitable for cutting bones, hard and streaky meats, and coarse fiber vegetables.

Variety

Western Kitchen Knife has wide-ranging varieties with various purposes.

 

Because western cuisine is composed mainly of meat, there are many kitchen knives, especially just for cutting meat, such as Gyuto knife (chef’s knife), Sujibiki knife (meat carving knife), Nikukiri knife (meat chopper knife).

 

However, on the other hand, there are also kitchen knives used for slicing and peeling vegetables, fruits, bread, such as a petit knife (small knife) and bread cutting knife.

 

Recently, even one kind of western kitchen knife is being used extensively.

 

For example, if you have a gyuto knife, not only for cutting meat, you also can use it for carving and skinning the meat. You also can use it for another raw material.

 

Santoku kitchen knife (all-purpose kitchen knife) is often used in a Japanese family.

Gyuto Knife (Chef’s Knife)

Originally, it’s a thin, long-blade-cut knife, primarily to slice and disjoint significant cuts of meat (carcass).

 

It is widely available in various sizes, from 18 cm for household use such as vegetables and bread cutting, up to 40 cm for meat cutting.

Japanese knife / kitchen knife that compatible with delicate beauty of Japanese cuisine

It is a Japanese kitchen knife used mainly in Japanese cuisine.

 

Japanese people have a fixation to be very particular about Japanese cuisine as their meal. Their cooking is very delicate. Even with the cutting operation such as carving or peeling, it can be said that it is a series of detailed work requiring the accuracy of the chef’s fingertip.

 

Japanese knives have developed while adapting to the delicacy of Japanese cuisine. It is said that the prototype is from the Japanese sword, and its sharpness can be said to be identical to the Japanese knife.

 

learning_knives_05

Structure/How to Cut

Many Japanese knives are based on a single-edged structure. The back is a flat surface, with only an oblique grinding surface on the front side. When you look at the cutting edge from the side, the section looks like the letter ‘L’.

 

Compared to a double-edged structure, a one-edged design is easy to separate from the blade when cutting food, making it possible to perform operations such as carving and stripping quickly. The primary technique is the hikikiri (cut by pulling) technique. Using the entire blade, slide while pushing and cut it off. By slicing while sliding the edge, you can cut it at a sharper angle than the actual kitchen knife blade so that you can finish the cut surface more beautifully.

 

When cutting soft food materials like fish, cut it with the hikikiri technique so that the meat tissue is not destroyed that much, and the beauty of cut surfaces from the sashimi stands out.

 

learning_knives_02

Variety

Japanese knives have their function according to the food materials, and various kinds of knives are made depending on the application.

 

For example, you use the Deba bocho (pointed carving knife) to cut soft raw materials like fish and chicken meat. If you’re going to do a delicate slicing method such as making Sashimi, you can use Sashimi bocho (sashimi knife).

 

If you want to cut vegetables, you can use Nakiri bocho (a Japanese knife for cutting vegetables).

 

While Nakiri bocho is used for regular use in the household, Usuba bocho (thin knife), which is also for cutting vegetables, is widely used by a professional chef because Usuba bocho is suitable for peeling and satisfactory quality.

 

Unlike Western knives, Japanese knives are also prepared for right-handed and left-handed users.

Deba bocho (Deba Knife)

Deba bocho is primarily used for cutting fish, and chicken.

 

The blade is thick and heavy, and the shape is a triangle. So even if you put your strength, you can use the cutting edge without bending.

“Do they really have that many kinds of knives?”
I think many people were surprised by the variety of kitchen knives.

 

Although this kitchen knife is plenty prepared, there are many other unique things that professional chefs use.
So, when we want to use it at home, what kind of kitchen knife should we choose?

 

Next, we would like to see which kitchen knife is best for the household according to the ingredients and uses.

How to Choose Kitchen Knife

Choosing according to the raw materials

There are various kinds of knives, and it’s a good idea to choose which kitchen knife is best depending on the raw ingredients and art of cooking.

 

We will introduce it separately depending on the circumstances for your reference when you are unsure what kind of kitchen knife you should choose and use.

To Cut Meat

■ General cut of meat: Gyuto Knife
■ To cut the muscle part: Sujibiki Knife
■ To cut meat from bones: Honesuki Knife

To Cut Fish

■ To cut and fillet: Deba Knife
■ To cut into Sashimi: Sashimi Knife

To Cut Vegetables

■ To cut: Nakiri Knife
■ Peeling and decorating: Usuba Knife

To Cut Bread

■ To slice: Bread Knife

To Cut Fruit and Small Ingredients

■ Slice and Peeling: Petit Knife

To Cut Any Raw Ingredients

■ To cut meat, fish and vegetables: All-purpose Knife

As you can see above, the same kitchen knife is different depending on the application for meat, fish, and vegetables. Originally, it is best to use it correctly according to its function, but it may not be easy to arrange all the knives above.

 

So, if you want to cut meat, you can use the general knife for meat, use ‘gyuto knife’,
if you’re going to cut fish, you can use the relatively short in length and easy to store, use ‘deba knife’,
and if you’re going to cut vegetables, you can use the general knife for vegetables, use ‘nakiri knife’.

 

With that, we think it’s good to prepare one for each different raw ingredient.

 

But, if you can’t prepare any knives and want a multi-purpose kitchen knife that can be used for all ingredients, we recommend the multi-purpose kitchen knife called ‘santoku knife’.

Choose by Material of Kitchen Knife

Besides choosing knives according to the application, it is also essential to select the material of your kitchen knife.

 

Depending on what material is used for kitchen knives, their properties are considerably different, and the care method will also be other.

 

Please make yourself a reference while considering your preference of knife, whether to choose it by sharpness, rust-resistant, easy sharpening, etc.

Steel (Carbon Steel)

It is a hard metal-containing iron as its main component with carbon, silicon, manganese, etc.

 

Carbon steel which contains carbon in general is used for a kitchen knife. Steels containing carbon are more suitable for making knives than iron with a purity of 100% because they can raise the hardness at once by adding heat when tempering.

 

steel_01

 

The most remarkable feature of a knife using steel is its sharpness.

 

On the other hand, it also has the disadvantage of being quickly getting rust.

 

Because the carbon contained in it is weak against rust, it will rust if you leave it without regular maintenance. However, in terms of sharpening, steel knives are generally easier to sharpen than stainless steel knives.

 

That’s why it is highly recommended for those who don’t have time to spare for sharpening by themselves and want to use it for a long time.

 

steel_02

 

Steel for a kitchen knife is famous for the material called ‘Yasuki steel’.
Yasuki steel is steel manufactured at Hitachi Metals. There are types such as blue paper steel and white paper steel.

Blue Paper Steel

It is used for high grade kitchen knife.

 

Components such as chromium and tungsten have been added to the blank steel. Chromium is a component that strengthens the steel and makes it hard to rust. On the other hand, tungsten prevents property change during heat treatment and increases the hardness of steel. As a result, it has superior strength, rust resistance, and abrasion resistance than plain paper steel.

 

It has a very sharp cutting edge.
Its sharpness is said to be the highest peak among the materials of the kitchen knife.

 

As a result, many professional chefs and other professionals are using it.
It is more expensive than the white paper steel.

White Paper Steel

It is steel that removes impurities such as phosphorus and sulfur, which deteriorates the properties of steel.

 

The sharpness is somewhat inferior to blue paper steel.
It has unique sharpness that you can use to cut hard food ingredients.

 

Blue and white paper steel are distinguished from No. 1 and No. 2 from those with more carbon, depending on the carbon content.
The higher the carbon content, the better the blade’s hardness (sharpness) and its resistance.
In addition, blue paper steel has the rank of ‘Super Blue Steel’ as the highest quality.

Stainless Steel

Actually, stainless steel is the same metal like steel.

 

Although iron is the main component, both are classified according to the content of elements such as carbon and chromium.

 

Compared with carbon steel, stainless steel has a minimal amount of carbon, and conversely, it is a metal that contains a lot of chromium. Carbon has the property of being rusty. On the contrary, chromium has a rust-resistant component.

 

Therefore, stainless steel is hard to get rusty and has the advantage of excellent durability.

 

stainless_01

 

The rust-resistant ability is the greatest asset of stainless steel.

 

Although it doesn’t get rust, it isn’t comparable with steel. The stainless-steel knife’s sharpness is still inferior to steel.

 

For that reason, it has been said that stainless steel knives are not suitable for business use.

 

However, in recent years, efforts have been made to add a small amount of carbon to stainless steel, and many stainless knives with hardness and toughness (tenacity) have appeared.

Molybdenum Steel

Molybdenum is a material added to stainless steel.

 

When molybdenum is added, steel can be kept without deteriorating its properties and maintain its strength even at high temperatures. Adding molybdenum is very advantageous, even in small amounts.
Generally speaking about the stainless-steel knife, there seems a lot of stainless steel knives using this molybdenum steel.

 

Molybdenum vanadium steel is made by adding vanadium in addition to molybdenum.
Vanadium is a component that makes steel stronger. It improves abrasion resistance.

 

By adding these two components to stainless steel, the strength of stainless steel increases even though the stainless steel has a weak point.

Ceramic

It is made of non-metal zirconia ceramic material.

It is characterized by its high strength, intense heat, and lightweight.
