Upgraded fishing tool for reliable hook and small blade sharpening. - Dual-surface grinding: one fine mesh for precise touch-ups and a coarse 180-mesh surface for faster material removal. - Long-lasting design: side grooves and 2V grooves reduce wear and extend the life of the sanding hook. - Two thickness options: two grinding surfaces with different thicknesses to meet varying sharpening needs from light hook touch-ups to deeper blade work. - Compact and compatible: compact form fits in a tackle box and is designed to work with standard hook-sharpening setups and small knives. - Clear benefits: improves edge quality, reduces downtime, and makes field maintenance easier. - Use scenarios: - On a boat or in the field, refresh dull hooks between casts. - At home, sharpen small kitchen knives or tackle blades for clean cuts. - In the workshop, restore edges on hooks and micro-blades during routine maintenance.
