This heavy-duty bypass lopper is designed for cutting very thick and strong branches on mature trees and vines. The cutting blade of this lopper slides past a counterblade in a scissor action, hence the name “bypass”. The pivot bolt of the Bahco lopper is offset from the natural centre-line of the tool. This unique design feature creates a slicing motion during cutting, which greatly assists the pruning of live wood and spreads wear over a larger area of the blade for increased life.
