2-Position Curved Blades: Unlike straight blades which tend to push round shapes out of their jaws as they close, these curved blades are specifically designed to encircle and hold round wire in place throughout the cut. 2 differently sized jaw openings fit a wide range of wire diameters. Completely Clean Cut: Sharpened to a keen edge, the curvature in the blades slices smoothly and effortlessly through each layer, producing a completely clean cut of insulation, shielding, hair-thin wire-even fabric jackets or paper lining. Lean and Practical Grips: Single-layer vinyl grips offer a bit of comfortable cushion and provide a smooth, yet nonslip surface. They're slim, not thick and bulky, so they stay out of the way when space is tight and are always easy to handle, even with gloves on.
