A garden bypass lopper is a type of pruning tool used to cut through branches and stems. It has two blades that work like scissors, with one blade passing by the other as it cuts. The blades are usually made of steel and are designed to be sharp and durable. Bypass loppers are ideal for cutting live branches up to 1-1/2 inches in diameter, making them perfect for trimming trees and shrubs. They can also be used for deadheading flowers or harvesting fruits and vegetables.
