When your garden tools start losing their edge, restore the quality of the blades with Niwaki's handy Maintenance Kit. The kit includes three Japanese whetstones expertly crafted in Osaka with high-grade aluminum oxide.

• A #220 coarse, grinding stone for rough blades.
• A #1000 sharpening stone for regular sharpening.
• A #3000 honing stone for more detailed work.

All stones are small enough to access tight spaces and maintain just about every edged blade. Before use, soak the stones thoroughly, then use the concave side to work on hand pruners and curved blades, and the flat side for shears and other straight blades. Handle with care to avoid dropping.

Concave bottom of the stones is ideal for the curve of secateurs blades, and the flat edges are ideal for snips and clippers longer straight blades.
