Which tool is best suited for cutting large branches when pruning shrubbery?

Lopping shears are specifically designed for cutting larger branches when pruning shrubbery. They feature long handles that provide better leverage, allowing you to generate the force necessary to make clean cuts on thicker stems and branches, typically up to about 2 inches in diameter. This tool is ideal for maintaining healthy growth in shrubs and trees by helping to shape them and remove any dead or diseased branches.

The other tools listed are not suitable for this task. A hose bib is used for connecting hoses to a water supply and has no relevance to cutting. An increment borer is utilized for taking samples of tree cores to study growth rings, which is entirely unrelated to pruning. An implant gun is designed for inserting materials into trees rather than for pruning. Thus, lopping shears are the clear choice for cutting large branches effectively.
