Cold chisels are a commonly used tool in various industries and trades, but have you ever wondered why they are called “cold” chisels? The term “cold” in this context does not refer to their temperature, but rather to the method of their use. Unlike hot chisels, which require heat to be effective, cold chisels are used without any heating process. This makes them a versatile and convenient tool for many applications.
So, where did the term “cold chisel” originate? The word “chisel” itself comes from the Old French word “cisel,” which means “to cut.” This reflects the tool’s primary purpose – to cut or shape hard materials such as metal, stone, or wood. The term “cold” was added to distinguish these chisels from their heated counterparts, which were used in conjunction with a forge or other heating source.
One of the key benefits of using cold chisels is their ability to maintain their hardness and durability even without heating. This is due to the high-quality steel used in their construction. The metal is hardened and tempered to withstand the force exerted during cutting or shaping. This makes cold chisels ideal for heavy-duty tasks that require precision and strength.
In conclusion, cold chisels are called “cold” not because of their temperature, but because they are used without heating. They are a versatile and reliable tool for cutting and shaping hard materials. So, the next time you reach for a cold chisel, you can appreciate the craftsmanship that goes into creating such a durable and effective instrument.
What is a Cold Chisel?
A cold chisel is a hand tool used in metalworking and stone masonry. It is a sharpened piece of high-carbon steel with a beveled edge, designed for cutting and shaping materials such as metal, brick, and stone. The term “cold” refers to the fact that the chisel is used at room temperature, unlike a hot chisel, which is heated before use.
Cold chisels come in various shapes and sizes to suit different tasks. They typically have a flat, rectangular blade with a cutting edge that is angled to one side. The cutting edge is ground to a sharp point, allowing for precise and controlled cutting. The opposite end of the chisel usually has a handguard or a handle for holding and striking with a hammer.
Cold chisels are commonly used in metalworking applications such as chipping or cutting metal plates, removing weld beads, and shaping metal components. They are also used in stone masonry for cutting or splitting stones, shaping rocks, and removing unwanted material. Cold chisels are versatile tools that can be essential in various industries, including construction, automotive, and manufacturing.
When using a cold chisel, it is important to wear proper safety equipment, such as safety goggles and gloves, to protect against flying debris and accidental injury. Additionally, the workpiece should be securely held in place to prevent it from moving or slipping during the cutting process. Proper technique and caution should always be exercised when using a cold chisel to ensure safety and achieve the desired results.
History of Cold Chisels
Cold chisels have been used by humans for thousands of years, playing an essential role in various trades and industries. The history of cold chisels dates back to ancient times, when early civilizations discovered the need for cutting and shaping materials like stone, wood, and metal.
In ancient Egypt, chisels made of copper were used for woodworking and stone carving. These early chisels were most likely used with a mallet or hammer to provide the necessary force to cut through the material.
The ancient Romans took chisel technology further by using iron chisels. Iron, being a stronger and more durable material, allowed for more precise and efficient cutting. The Romans also developed different types and sizes of chisels to meet specific needs, such as flat chisels, point chisels, and gouges.
During the Middle Ages, blacksmiths played a crucial role in the development of chisels. They were skilled in forging and tempering chisels, making them even more robust and resilient for heavy-duty work.
The 18th and 19th centuries saw significant advancements in the production of chisels. With the Industrial Revolution, the introduction of new machinery allowed manufacturers to produce chisels on a larger scale. This led to improvements in design, making chisels more ergonomic and comfortable to use.
As the demand for chisels grew, so did the variety of materials they were designed to cut. Chisels were adapted for cutting through tough materials like hardened steel, cement, and concrete.
Today, cold chisels are widely used in construction, metalworking, and other industries. While modern technology has introduced electric and pneumatic tools for cutting and shaping, the simplicity and versatility of cold chisels continue to make them an essential tool in any tradesperson’s toolbox.

Origin of the Term
The term “cold chisel” has an interesting origin that can be traced back to the ancient days of metalworking. The word “chisel” itself comes from the Old French word “cisel” which means “cutting tool.” The term “cold” refers to the use of this tool without the need for heating it, unlike hot chisels which require heating before use.
In craftsmanship, the term “cold chisel” emerged to distinguish it from other types of chisels. It is believed that the term first appeared in the early 19th century, during the Industrial Revolution, when metalworking tools became increasingly important. The term “cold chisel” became widely used to describe this particular type of chisel that was used to cut and shape cold or non-heat-treated metals.
Unlike hot chisels and other metalworking tools that rely on heat for shaping and cutting, cold chisels are designed to be used at room temperature. They are typically made of high-carbon steel, which offers a high level of hardness and durability for working with various metals.
The term “cold chisel” has been passed down through generations of craftsmen and is still widely used today. It has become a common and recognizable term in the world of metalworking, construction, and woodworking.
Function of Cold Chisels
A cold chisel is a type of hand tool that is specifically designed for chiseling or cutting cold metal. It is typically made of hardened steel and has a sharp cutting edge. Cold chisels are widely used in various industries, including metalworking, construction, and automotive repair.
The primary function of a cold chisel is to remove unwanted material from a metal surface. This can include cutting through thick metal plates, removing rust or scale, and shaping or carving metal. Cold chisels are commonly used to create grooves, channels, or notches in metal. They can also be used to break or chip away small pieces of metal.
Cutting and Shaping
One of the main applications of a cold chisel is cutting and shaping metal. The sharp cutting edge of the chisel allows it to slice through the metal with ease. This is especially useful when working with thick or hardened metal, where other tools may not be as effective. Cold chisels can be used to accurately cut straight lines or create intricate shapes and designs on a metal surface.
Removing Material
Cold chisels are also valuable for removing unwanted material from a metal surface. This can include removing rust, scale, or excess metal from a workpiece. The chisel can be used to chip away at the material until the desired surface is achieved. Cold chisels are particularly useful for tasks that require precision and control, as they allow the user to remove material in small increments.
In conclusion, cold chisels play a vital role in metalworking and other industries. Their function of cutting and shaping metal, as well as removing unwanted material, makes them essential tools for various applications. The durability and sharpness of cold chisels make them effective and reliable tools for any job that involves working with cold metal.
Features and Types of Cold Chisels
Cold chisels are highly versatile tools used in various applications that require cutting or shaping metal. Here are some of the key features and types of cold chisels:
Durable Construction: Cold chisels are typically made from high-quality hardened steel, which ensures their durability and resistance to wear and tear.
Sharp Cutting Edge: The cutting edge of a cold chisel is usually ground to a sharp angle, allowing it to effectively cut into the metal surface.
