Which of the following tools is classified as a sharp-edged or pointed non-electric implement?

The correct choice is shears because they are designed specifically for cutting and have sharp blades that can effectively slice through various materials, such as fabric, paper, or even some food items, depending on their design. As a sharp-edged tool, shears are considered non-electric implements because they operate manually, relying on the user's physical effort to create the cutting action.

In contrast, hammers, screwdrivers, and drills, while they may have some pointed or sharp features, are not primarily classified as cutting tools. Hammers are impact tools used to drive nails or break items apart, screwdrivers are meant for turning screws, and drills, which can also be powered by electricity, are typically used for creating holes rather than cutting or slicing. Thus, shears stand out as the appropriate answer in this context for their specific function and classification.
