Which tool would you use for cutting and shaping shrubbery?

Pruning shears are specifically designed for cutting and shaping shrubbery, making them the appropriate choice for this task. They are equipped with sharp blades that can effectively cut through branches and stems, allowing for precise and clean cuts, which is critical for maintaining the health and appearance of shrubs. The handles are usually designed for easy gripping and leverage, giving the user the ability to apply sufficient force to cut thicker branches. This tool is commonly used in horticulture and landscaping, directly aligning with the need to manage and curate plant growth.

Other tools mentioned in the choices serve very different purposes. PVC cutters are primarily used for cutting plastic pipes, putty knives are intended for spreading or scraping materials like putty or paint, and socket wrenches are used for tightening or loosening nuts and bolts. Each of these tools fits specific functions and would not be effective for tasks related to shrub maintenance, highlighting why pruning shears are the best tool for cutting and shaping shrubbery.
