Best Sharpening Stones and Sharpeners for Garden Tools
Picked from Amazon listings, not hands-on tests. How we pick
Garden tools need a different sharpener from kitchen knives. Pruners and loppers have a single bevel on the cutting blade, often curved, and you sharpen only that bevel while leaving the flat back alone. Hoes, shovels and mower blades are thick, soft steel that needs fast, coarse removal, not a polish. And the work happens outdoors, often with the tool still on the plant or the mower on its side, so a sharpener you hold in the hand and stroke along the blade beats a bench stone. The main types are diamond files (fast, flat, work dry), carbide scrapers (very fast on soft steel, leave a rough edge), coarse pucks (good for heavy tools), and multi-tools that combine them. This guide compares seven by abrasive, grit and which tools each one suits.
