These high-quality sharpening stones are specially designed for secateurs, but are equally effective on shears, topiary clippers, and other sharp garden tools. Available in three grit levels, they cover everything from routine maintenance to restoring heavily worn blades.

The underside of each stone is subtly concave to match the convex curve of secateur blades, helping you maintain the correct angle while sharpening. The flat surfaces are ideal for sharpening shears and removing burrs from the reverse side of the blade. Compact and easy to handle, they can also reach tighter areas along the blade edge.

Regular use keeps tools performing at their best—sharper blades make cleaner cuts, reduce strain, and are safer and more satisfying to use.

Grit options

  • 220 (coarse): for rough or damaged blades—ideal for restoring edge and shape
  • 1000 (fine): the most versatile option, perfect for regular sharpening

Suggested Use

  • Soak until the bubbles stop rising (about 3 minutes) before sharpening.
  • Use the concave edge for secateurs, the flat sides for shears and burr removal.
  • Be gentle—stones are fragile and may crack if dropped.
  • Follow up with Niwaki Camellia Oil for rust prevention.
