The ST-A3.0 nippers utilize a single-bladed design that elevates the ability of a nipper to cut plastic smoothly and efficiently. The nipper is produced using specially forged steel that has undergone high-temperature smelting, allowing the Rockwell hardness of the blade to reach a rating of 58-64. The blade of the 3.0s is then carefully polished, creating a beautiful mirror-like surface that enhances the smoothness of the cut and improves the comfort of use.
In the development process, the blade has been tested to withstand more than 50,000 cuts on a 3mm plastic rod, ensuring the longevity of the blade. The handle of the nipper has utilized ergonomics in its design ethos, reducing stress on the hand and improving comfort. Improvements have been made to the rear of the nipper with the inclusion of a limiting rod and screw. This improvement effectively prevents damage to the nipper caused by excessive force or openings.
