The GodHand PN-120 Blade One Nipper is designed to be more durable and easier to handle than the SPN-120 Ultimate Nippers. The Blade One Nipper can cut translucent plastic up to 2mm compared to Ultimate nipper's 1mm. The single edged cutting blade is slightly thicker than the Ultimate Nipper, making the blade more durable but also slightly less ease of cutting compared to the Ultimate Nipper. Due to the design of the nippers, it is recommended the following: To not use excessive force when cutting. Cut as close to center of the blade as possible. Do not twist the blade while cutting or during releasing the blade. Do not cut if it doesn't fit within the length of the blade.
