Which of the following is a type of pruning tool?

One-handed shears are indeed a type of pruning tool specifically designed for precise cuts on smaller branches and stems in a vineyard or garden. These tools are essential for performing tasks such as thinning out grapevines, removing unwanted growth, and shaping the plant for optimal sun exposure and air circulation. Their design allows for comfortable handling and maneuverability, making them suitable for delicate pruning work where control is crucial.

In contrast, chainsaws are usually employed for larger, heavier cutting tasks and are not ideal for the precise work required in pruning grapevines. Both garden forks and trowels serve different purposes in landscaping and gardening; forks are used primarily for turning soil or breaking up clumps, while trowels are designed for digging, transplanting, or scooping soil. Therefore, one-handed shears stand out as the most appropriate and specialized tool within the context of pruning.
