How can you gain additional leverage when using a screwdriver?

Using an adjustable wrench can provide additional leverage when using a screwdriver in certain situations. Specifically, if the screwdriver has a flat, wide blade, the adjustable wrench can be clamped onto the handle of the screwdriver, allowing for a stronger grip and increased torque. This setup helps when dealing with tight or rusted screws that require more force to loosen. The leverage from the wrench can amplify the rotational force applied to the screw, making it easier to turn, especially if manual torque alone is insufficient.

In contrast, the other options may not effectively increase leverage in the same way. A rubber grip can improve comfort and control but doesn't physically enhance torque. A longer screwdriver does allow you to reach screws that are further away, but the additional length alone does not necessarily equate to more leverage; it can sometimes lead to less control. Lastly, while a power drill provides significant torque for driving screws, it operates differently than manual methods and doesn't fit the traditional concept of "leveraging" a tool in the same mechanical sense.
