1. Top reinforcement screw design - The honing guide uses three top reinforcement screws to hold the chisel firmly in place during sharpening, eliminating any risk of lifting or tilting for a stable, predictable result. 2. Adjustable for precision - Easily adjust the distance between the chisel and honing guide to set your desired grinding angle. - Refer to the built-in angle chart and ruler for accurate measurements before sharpening. 3. Wide roll for stability - The widened roller improves stability, allowing you to roll the cutter back and forth smoothly while maintaining the correct angle for effective sharpening. 4. Compatibility - This jig is suitable for chisels or aircraft with widths from 0.0 cm to 55 inches, enabling use with a variety of tools by adjusting the length of the clamped object to the protractor scale. 2-3 practical use scenarios - Woodworking chisels: Maintain consistent bevels and sharp edges on chisels used for joinery, paring, and planing, improving cutting quality and control. - General edge maintenance: Re-sharpen or restore edges on tools within the stated width range, ensuring repeatable angles and clean, precise cuts. - Precision work with varied tools: When working with multiple chisels or similar tools, quickly adjust the position to match different bevel angles, using the angle chart and ruler for accurate setup.
