reinforcement screw design: Three reinforcement screws securely hold chisels in place, preventing lift or tilt during sharpening for consistent results. Adjustable for precise angles: Easily adjust the distance between the chisel and honing guide to achieve your desired grinding angle for every sharpening task. Widened roller for stability: The widened roller enhances stability, enabling smooth backandforth movement while keeping the correct angle for effective sharpening. Compatibility: Accommodates chisels or planes with widths from 0 to 55 inches, making it suitable for a range of woodworking tools and projects. Use scenario: Regular chisel maintenance — sharpen chisels of varying widths with stable guidance to maintain a clean, true edge. Use scenario: Plane blade sharpening — keep bevels consistent on plane irons and other blades with reliable angle control. Use scenario: Fine woodworking and hobby projects — achieve precise bevels and clean edges for joinery, dovetails, paring, and detailed carving.
