What type of power tool requires upper and lower guards?

Explanation:
Tools with exposed rotating blades must be fully guarded to protect you from contact and flying debris. A portable circular saw is designed with two blade guards: an upper guard that covers the blade above the work and retracts as you start the cut, and a lower guard that protects the blade portion near the base as it moves through the material. This setup keeps the blade shielded when not cutting and during entry and exit of the cut, which is why it’s the type of tool that requires both upper and lower guards. Other tools may have a single guard around the wheel or blade, but not the paired guards characteristic of a circular saw.
