The ratchet pruner can be used to cut stems and branches, suitable for gardeners. With the ratcheting anvil pruner, you can easily cut through thick branches that ordinary trimmers wouldn't stand a chance against! The ratcheting mechanism multiplies the power of your hand. Stainless steel spring with professional segmented lever, more labor-saving and safer. Cut into the branches and tighten, they lock (click) and go to the next setting. Then release and repeat until the cut is complete. The heat-treated, hardened SK5 alloy steel blades are ultra-strong, sharper and will last longer, less likely to nick or need frequent sharpening. They are coated with non-stick Teflon which resists sap and other sticky materials. Strong lightweight aluminum body and ergonomic handles are comfortable and help reduce strain/fatigue. The rubber coated handles are comfortable and non-slip. Sliding safety lock, easy to use and handle. Hold firmly and close, push down to lock otherwise unlock.
