Compatibility and construction - Aluminum bracket designed for woodworking machines such as planers, providing a sturdy, all-metal platform for sharpening and blade handling. Precision sharpening control - The plane knife can be adjusted by changing the distance between the tip of the chisel and the grinding guide rail to achieve a standard sharpening angle. This enables consistent, repeatable edge geometry. Blade compatibility and adjustment - The holder attaches chisels and planer blades up to 0.66 mm wide, with an adjustable button to cover common sizes. Quick setup ensures correct blade fit without guesswork. Durability and design - Built from durable all-metal material with an extended roller design to facilitate smooth sharpening and reduce wear, helping to keep blades from rusting over years of use. Use scenarios - Scenario 1: Planer blade replacement and sharpening Attach the planer blade in the holder, adjust the distance to set the standard sharpening angle via the grinding guide rail, and sharpen edges consistently before re-installation. - Scenario 2: Routine chisel maintenance in a craft shop Use for chisels up to 0.66 mm wide; adjust the button to fit blade size, and maintain uniform edge geometry for precise planing work. - Scenario 3: Small workshop setup with limited space The extended roller design aids smooth feeding of blades in tight spaces, while the all-metal, rust-resistant construction supports long-term reliability in various workshop conditions.
