What feature distinguishes a wood-cutting chisel from a metal-cutting chisel?

The distinguishing feature between a wood-cutting chisel and a metal-cutting chisel is indeed the type of cutting edge. Wood-cutting chisels typically have a beveled cutting edge that is designed to create clean cuts in wood fibers without splitting them. The edge is often ground to a specific angle that is optimal for cutting through wood, allowing for greater control and precision.

On the other hand, metal-cutting chisels are crafted with a different edge geometry that helps them effectively shear metal. This can include sharper angles or additional hardness to withstand the increased resistance encountered when cutting through metal materials. The design is tailored specifically for the properties of the material being worked on, ensuring that the chisel performs optimally for its intended use.

The other options do not inherently distinguish these types of chisels. The material of the handle can vary for both wood and metal chisels and does not serve as a defining characteristic. Similarly, the size of the blade and the color of the finish can differ among chisels within each category, but these features do not provide a clear distinction between wood-cutting and metal-cutting chisels.
