How It Works

Before use, soak each stone thoroughly in water. Then use the concave side to follow the curve of secateurs and other pruning blades, and the flat side for shears or straight edges. Work along the blade at a steady angle until you feel the edge return. Handle with care and avoid dropping the stones.

What’s Included

#220 coarse grinding stone – for worn or damaged blades


#1000 sharpening stone – ideal for regular sharpening and maintenance


#3000 honing stone – for detailed work and a fine, polished edge

All three stones are compact enough to reach tight curves and corners on most garden tools.

Best For

Designed for maintaining:


  • Hand pruners and secateurs

  • Garden shears and clippers

  • Snips and smaller cutting tools

  • Other carbon-steel blades that need a clean, sharp edge

Perfect for gardeners who want professional results without sending tools away for sharpening.

Use & Care Tips

  • Soak stones in clean water before each use.

  • Use the #1000 grit for most general sharpening sessions.

  • Sharpen secateurs every couple of weeks and shears every time you use them for best performance.

  • After sharpening, rinse stones, let them dry fully, and store in a dry place.

  • Wipe your tools clean, apply a light coat of oil, and store away from moisture.
