Why you need this tool Produces clean, consistent 90° edges for internal and external corners, saving time on rework and reducing material waste. Smooth, burr-free surfaces simplify cleaning and lower routine maintenance, keeping the tool ready for the next job. Ergonomic, non-slip grip and a robust stainless-steel body reduce fatigue and extend service life, delivering reliable results day after day. Key features and benefits Burr-free finish: Manufactured with advanced cutting techniques to create a smooth, deburred surface that is easy to wipe clean and prevents buildup that can affect accuracy. Precise edge control: A powerful edge mechanism ensures sharp, accurate 90-degree surfaces with minimal deviation, ideal for both internal and external corner applications. Durable material: Thickened stainless steel improves bending strength and corrosion resistance, supporting consistent leveling, shaping, and edging across multiple processes. Comfortable handling: Ergonomic curved handle with a non-slip surface improves grip, balance, and force distribution for longer use without discomfort. Function, compatibility and performance Functions: Leveling, shaping and edging with precise 90° results. Compatibility: Designed for use on internal and external corners and compatible with typical finishing materials used in drywall, plaster and cement-based repairs. Performance: Robust construction and precise mechanism minimize deviations and deliver repeatable, professional-grade edges. Typical use scenarios 1. Drywall finishing: Create crisp 90° inside and outside corners after taping and joint compound, reducing sanding and touch-up work. 2. Plaster and skim coat work: Level and shape edges for a uniform finish before painting or texture application. 3. Repair and retrofit jobs: Quickly restore damaged corner profiles on cementitious patching or finishing compounds without frequent tool replacement. Materials: Thickened stainless steel body with an ergonomic, non-slip curved handle. Functions: Multi-process edging, shaping and leveling for internal and external corners. Performance: Smooth, burr-free surface for easy maintenance; precision edge mechanism for minimal deviation.
