Beginner's sharpening jig/guide for garden and hand tools.

A beginner gardener seeking specific angle instructions for sharpening a shovel highlights a need for an easy-to-use tool or guide. A simple, physical jig or a comprehensive, video-based instructional resource specifically designed for beginners to consistently achieve correct sharpening angles for common garden and hand tools (like shovels, hoes, axes) would be very beneficial, bridging the gap between 'eyeballing' and precise sharpening.
