What is a common identifier for the type of chisel used in carpentry?

In carpentry, the shape of the cutting edge is a key identifier for the type of chisel being used. Different chisels are designed with specific cutting edge shapes that suit various applications. For instance, a firmer chisel has a straight cutting edge ideal for general purpose tasks, while a skew chisel angles the edge for precise corner work. The unique profile allows carpenters to select the right tool for the task at hand, ensuring efficiency and effectiveness in their work.

While characteristics like bevel angle, weight, and handle length can influence a chisel's performance or handling, they do not serve as primary identifiers for the specific type of chisel. The cutting edge shape directly correlates with its intended use, making it the most important distinguishing feature among the various types of chisels. Understanding these differences aids carpenters in making informed choices about the tools they select for their projects.
