What is the primary characteristic of a mallet?

The primary characteristic of a mallet is that it is a striking tool with a rounded head. This design allows it to deliver force effectively while minimizing damage to the surface of the material being struck. The round shape helps distribute the impact over a larger area, reducing the likelihood of marring or denting softer materials.

In contexts such as woodworking or assembly, using a mallet is advantageous because it can be employed to tap joints together without risk of splitting the wood or damaging a delicate surface. The mallet's construction typically features a non-marring material like rubber or wood, which further supports its function as a gentle striking tool.

This specific characteristic distinguishes the mallet from other tools, such as hammers, which usually have a flat or more pointed striking surface, offering a different impact style.
