The rubber handle is designed according to ergonomics, which is comfortable to hold, easy to operate and more adaptable. 【Strong-sharp blade】The blade is sharp, which can easily strip the thread. It will not damage the optical fiber core when stripping the outer cable. The blade is not exposed, and it can prevent blunt objects from colliding with the blade and causing damage to the blade. It also can prevent the blade from scratching the user. 【Applicability】Adaptive range: Indoor 3mm (W) * 2mm (H) optical cable; Adaptive optical fiber: 1/2 core optical fiber; Adaptive coating diameter of optical fiber: Φ0.25mm & Φ0.9; Adaptive cladding diameter of optical fiber: 125μm.
