Chisel: Tools for Shaping Wood, Stone, and Metal
A chisel is a hand tool with a sharpened blade used to cut, pare, or shape material. This article describes types, parts, history, common uses, maintenance, and safety.
Overview
A chisel is a handheld cutting tool with a straight or shaped blade and a handle, designed to remove material by cutting, carving, or splitting. Chisels are made for a range of materials — most commonly wood, stone, or metal — and are often used in combination with a mallet or hammer (hammer) to deliver controlled force. Professional woodworkers, stonemasons, metalworkers, and sculptors all rely on chisels to produce precise forms and fittings.

Parts and characteristics
Typical components include a cutting edge, a blade or bit, a shoulder or ferrule that reinforces the handle, and the handle itself. Blades vary in profile (flat, beveled, curved) and in thickness according to intended use. Blade steel is usually hardened and tempered to hold a keen edge; handles are commonly wood, plastic or composite. The angle of the bevel and the hardness of the steel determine how a chisel behaves: low-angle, thin blades pare and slice; heavy, thick blades withstand hammer blows and rough work.
Common types
- Woodworking chisels: bench chisels, mortise chisels, paring chisels and skew chisels for joinery and fine shaping.
- Carving chisels and gouges: chisels with curved profiles used by sculptors for wood or stone carving.
- Masonry chisels: designed to cut or split stone and concrete; often struck with a club hammer and used on materials like stone and marble.
- Cold chisels: hardened steel tools used to cut metal by striking with a hammer.
History and development
Chisels are among humanity's oldest tools. Early examples appear in prehistoric contexts where sharp stone flakes were used to cut and carve. With the development of metallurgy, bronze and later iron and steel chisels became common, improving durability and edge retention. Over centuries craftsmen refined blade shapes and tempering methods; modern manufacturing adds alloy steels and ergonomic handles for greater performance.
Uses, examples, and technique
Chisels make joints, shape decorative details, hollow mortises, carve sculptures, and remove excess material during demolition. Wood chisels are typically used with a wooden mallet or pushed by hand for fine paring; masonry and cold chisels are struck with heavier hammers for forceful cutting. Effective use requires securing the workpiece, supporting the cut, and controlling chip flow so material splits cleanly rather than tearing.
Maintenance, safety, and distinctions
Keeping a chisel sharp is essential: edges are honed on stones, strops, or grinding systems and often finished with a fine hone. Inspect handles and ferrules for damage to avoid splitting under impact. Safety precautions include wearing eye protection, clamping the work, and using the correct chisel type and striking tool. Chisels differ from related tools such as planes or files by removing material with a singular cutting edge rather than abrasion or shaving.
For practical guidance and tool selection, consult manufacturer instructions or instructional resources (wood and carving guides) and introductory references (hammer and striking technique) to match chisel type to task.

Milling chisel
Rotating drums fitted with cutting tools are used on cold milling machines in road construction. The cutting tools are shaped like a spinning top and are replaceable.
Drill bit
→ Main article: Drill bit
In deep drilling technology - mostly for the purpose of developing oil and gas deposits - drill heads known as bits are used. The most common form for this purpose is the roller bit, in which toothed bevel gears crush the rock to be drilled through as the bit rotates. Special gouges are commonly used for soil sampling, see Pürckhauer drill bit.
Chisel (Archaeology)
Here, chisels are treated as an object of exploration. (Chisels, on the other hand, can also serve as tools of search in archaeology).
Chisels are long, narrow working tools, which served for chipping. The cross-section may be rectangular or octagonal, round or square. The width of the cutting edge is about the same as the thickness, the length is about 15 cm. The chisel is a shape-changing tool, which is struck with another device. For example, wood and striking stones were suitable as mallets. The chisel can be driven into a material with measured blows (e.g. when splitting whalebone, bone or antler). The gouge is concave (curved inwards) towards the cutting edge and is used for hollowing.
Prehistoric chisels are made of flint, rock, antler, bone, dentine, e.g. from mammoth or amber. They were mainly used in levallois and chipping techniques. They have been known since the end of the Palaeolithic, but were most widely used as narrow or hollow chisels in the Neolithic. Ewald Schuldt found 60 flat and 36 gouges in 106 megalithic sites in Mecklenburg-Vorpommern. The oldest ground bone chisel comes from Přezletice in the Czech Republic and is about 700,000 years old.
The first evidence of chisels made of almost pure copper by smelting dates back to the 6th millennium BC from what is now Serbia (Pločnik). Their cutting edges were cold forged and thus hardened.
