Loppers are used to cut branches and small saplings, usually up to 2” in width. The long handles let you reach far and exert high leverage with minimal exertion, letting you comfortably cut anything that can fit entirely between the blades when they are open. Typically, this includes wood of up to one inch in diameter or more, but for most of your cuts on much smaller wood, you’ll prefer the accuracy and one-handedness of pruners over loppers. For thicker wood, you’ll need a pruning saw.
