For flooring installers working with PVC or vinyl, this skiving knife is an essential tool that makes clean, professional edges so much easier! The 130mm (5.1 inch) total length gives you good control for detailed work. The three included blades are the real value - you can switch between them for different tasks and locations. The aluminum alloy handle has a comfortable grip that reduces hand fatigue during long installation jobs. The blue color oxidation won't peel off, so it maintains a professional appearance. This tool is specifically designed for creating those perfect阴阳 corners on walls and preparing PVC floor flanging for welding. The welding rod leveler function helps smooth electrodes for seamless results. What I really appreciate is the plastic storage case - it keeps all three blades organized and prevents losing them on job sites. The high-speed steel blades stay sharp through extensive use and make clean cuts without tearing the material. Whether you're doing residential or commercial flooring installation, this tool helps achieve those factory-looking welded seams that separate amateur work from professional results. The ergonomic design really makes a difference when you're working on your knees for hours. For the price and including multiple blades, this is an absolute must-have for any serious flooring installer working with welded seams.
