[Two Opposing Carbide Wheels – Precise Cutting]: Featuring hardened cutting wheels on both jaws, this tool grips and cuts material from both sides simultaneously. It delivers a clean break in a single, controlled action—eliminating the need for separate scoring steps and reducing material waste. [Return Spring – Reduces Hand Fatigue]: Unlike standard nippers, the built-in spring automatically opens the handles after each cut. You only need to squeeze to cut, which significantly reduces wrist strain during long mosaic or tiling projects. [Safety Lock – Secure & Compact]: The sliding lock keeps the jaws firmly closed when not in use. This prevents accidental pinching in your toolbox and protects the precision carbide wheels from damage during storage. [Pre-Oiled Pivot – Wipe Before Use]: A protective anti-rust oil coating is applied to the carbon steel pivot for durability. Please wipe the tool with a dry cloth before first use. Do not rinse with water, as this will cause the steel to rust. [Important Note]: Always wear safety goggles to protect against sharp fragments. A slight oily film on the surface is normal—it ensures smooth operation and prevents rust. Thank you for your understanding., Manufacturer: AURVIX
