Which of the following is NOT a characteristic of a carpenter's pencil?

A carpenter's pencil is specifically designed for durability and functionality in the trade, which is reflected in its characteristics. Thicker lead is a key feature because it resists breaking and provides a clear, bold mark on various materials, which is essential for visibility during the building process. The flat shape of the pencil is important as it prevents it from rolling away and can be sharpened to a fine point for precision marking. An ergonomic design, while not always a focus, enhances comfort for the carpenter during extended use.

Bright colors, while they may help in visibility in some contexts, are not a standard characteristic associated with carpenter's pencils. These pencils are typically made in subdued colors such as yellow or red, which, while still visible, do not distract from the task at hand. Therefore, this characteristic stands out as the one not typically aligned with the essential functions a carpenter’s pencil is designed to fulfill.
