Know before you buy
Yes, you must soak the stones in water before use. This ensures they are properly lubricated and prevents the aluminum oxide from clogging during the sharpening process.
The kit is designed with two distinct profiles. Use the concave side for the curved blades of secateurs to maintain their shape, and use the flat side for straight blades like shears and clippers.
Each grit serves a specific stage of maintenance. The #220 stone is for removing nicks or rough grinding, the #1000 stone is for regular sharpening, and the #3000 stone is for honing the edge to a fine, finished state.
Yes, the stones are intentionally compact. Their size allows you to maneuver into tight areas on your tools that larger, standard-sized sharpening blocks cannot reach.
These stones are crafted in Osaka, Japan, using high-grade aluminum oxide. This material is chosen for its durability and consistent performance when sharpening hardened steel blades.
