It’s a fact that whenever you go into the kitchen to do some cooking, a knife is something you will use every time. When dealing with kitchen knives, we must know some basic facts about it so that we can utilize this awesome tool to its maximum. Let’s find out what the knife is.
What is a kitchen knife?
“A knife is a tool with a cutting edge or blade attached to a handle.
Humankind’s first tool, knives were used at least two-and-a-half million years ago, as evidenced by the Oldtown tools.
Originally made of rock, bone, over the centuries, in step with improvements in metallurgy or manufacture, knife blades have been made from bronze, copper, iron, steel, ceramics, and titanium.
Although most modern knives have either fixed or folding blades, blade patterns and styles vary by maker and country of origin”. wikipedia
Types of Kitchen Knives:
Generally, there are 3 types of knife shapes used and manufactured around the world.
- French Knife
- German Knife
- Japanese Knife
French knife is straighter along the cutting edge, and it curves upward to the tip.
Japanese knives are basically the Japanese version of French knives.
Let us explain some physical characteristics of a Japanese Knife.
Physical characteristics Of a Japanese Knife:
Japanese Knives come with 2 types of blades
- Forged Blades
- Stamped Blades
They are manually processed by skilled labors and workers.
The blades are heated and beaten to form a shape and then sharpened.
They are also called full-tang (one piece), i.e., the mettle of the knife starts from the very tip of the blade to the far end of the handle.
They are cut directly from the cold rolled sheet, undergo heat treatment to get the strength, sharpened, and finally polished.
Here, we can further divide these 2 types of blades into 4 sub types.
- Carbon steel blades
- Stainless steel blades
- A laminate of both
- Ceramic blades
Carbon Steel Blades:
Carbon steel blades are made up of the mix of iron and a percentage of carbon.
The chefs and cooks of Asia and middle east like and prefer this type of blades to use in daily routine.
Stainless Steel Blades:
These blades are an alloy of iron, chromium (resist rust and corrosion), and Nickel.
It has a very low percentage of carbon.
The stainless-steel blades come with a high grade of steel and are extremely sharp.
It easily outperforms carbon blades.
A laminated knife is the mix of both hard and breakable steel.

Structure of a Japanese Knife
Japanese kitchen knives are generally used for food processing.
The steel used to make these knives is also used to make Samurai swords.
These knives consist of 4 common characteristics.
Japanese handles are generally made up of wood, which is burned and friction-fitted to an inner tang. A buffalo horn bolster caps the handle of the blade.
A common shape in Japanese handles is D-shape, has a ridge running along one side, and mostly right side for right-hand use.
Chefs who like to use big and heavier knives often choose Japanese knives for their daily food processing work.
During the period of the 1860s – 1890s, Japan adopted French and German cutlery traditions and merged it with their own cutlery traditions and techniques.
Japanese divide their knife blades into 8 different types, and every blade type carries its own characteristics.

Talking about the making or construction of a Japanese knife, there are two types of blades.

Monosteel blades are thinner than laminated blades and are harder to sharpen.
Laminated blades are a mix of 2 types of steel.
Both of them contain steel and carbon, which makes the knife easy to sharpen, corrosive, and shock resistant.
When you are searching for the perfect knife to have in your kitchen, it all depends on your preferences and use.
What am saying is that no knife is perfect. There are, and always will be, some pluses and some minuses with every kind of knife. But the choice gets a bit easier when you break down your choice of knife by asking yourself, “I need a knife for what purpose?”
Some prefer the stainless steel look of the knife, while some prefer carbon knives. Some are expensive, and some are cheap. But none of them will burn a hole in your pocket.
