Jameson JA-34DP Double Pulley Big Mouth Pruners are made with the same heavy-duty construction as Jameson’s JA-14 Pruners but have a larger cutting capacity. They also feature a removable upper spring pin and blade bolt for easy blade replacement and sharpening—no more drilling out pins to replace your blades! The Jameson JA-34DP Double Pulley Big Mouth Pruner provides additional leverage making it easier to pull and cut and includes an adapter.
