What should a screwdriver's blade look like to be considered in good condition?

A screwdriver's blade should be flat to be considered in good condition. A flat blade allows for effective torque transfer when driving screws, which is vital for both performance and safety. The blade needs to fit snugly into the screw head to prevent slipping, which can lead to damaged screws or injury. If the blade is curved, it could indicate misuse or wear, negatively affecting its ability to drive screws properly.

A pointed blade would not be appropriate as it does not correspond to traditional screwdriver designs, and instead references a category of tool used for different purposes, such as prying or digging. A pitted blade is also a sign of corrosion or damage, which could compromise the structural integrity of the blade and make it unsafe to use. Therefore, a flat blade clearly meets the requirements for functionality and safety in tools used for electrical and mechanical tasks.
