The Corona Clipper stratashear 26-inch professional bypass lopper features a 2-1/2-inch cutting capacity and Corona's new stratashear technology. Stratashear is a patented three-stage system used to reduce friction and improve cutting efficiency. The stratashear technology consists of a radial arc coupled with a forged Coronium steel alloy blade for abrasion resistance. Next, a fluropolymer layer is added, giving the blade nonstick, continuous lubrication. The result of the stratashear combination allows for cutting up to 32-percent easier than standard loppers. The bypass blades can be re-sharpened, and the light, sturdy aluminum handles feature Corona's ShockStop bumpers to reduce fatigue. The lopper comes with a limited lifetime warranty.
