Free Sharpening Stone Included: The blade is sharpened at an angle of about 20° by sliding it back and forth on the sharpening stone while maintaining even pressure and speed. This process quickly restores blade sharpness and extends its lifespan. Smooth and Crack-Free Cuts: Innovative wide blade blades reduce the contact surface between the blade and the object, reducing cutting resistance, resulting in faster cutting speeds, smoother and flatter cuts, while maintaining blade sharpness. Multiple Cutting Modes: In addition to regular straight cuts, various cutting modes are needed on construction sites for special scenarios, such as L-shaped corner cuts for pillars and door edges, and width cuts for walls. Multiple modes meet different requirements, improving work efficiency and cutting quality. 0.47in/12mm Cutting Thickness: Using genuine 0.47in/12mm mold steel blades, they are tougher and more durable than ordinary steel. Can easily cut various types of popular flooring materials, including laminate, vinyl plank (LVP, SPC, WPC, VCT, vinyl), and carpet tiles. Effortless Cutting: Utilizing the lever principle, by adjusting the bearing position to find the golden load-bearing point, combined with the hardness of aluminum alloy, and an extended handle to amplify the force instantly, easily cut through objects.
