🔧 What it does & how to use
This fine-grade emery whetstone is used by watchmakers and jewellers to sharpen and polish the cutting or working edges of small hand tools — such as gravers, screwdrivers and other bench tools — restoring a keen, smooth edge and removing burrs left by coarser stones or wear. Being a 3/0 (fine) grade, it's designed for the final finishing pass rather than heavy stock removal, so it suits both hobbyists maintaining their own kit and professionals doing precision tool upkeep on the bench.
-
Prepare the stone: lightly wet or oil the surface to help the stone cut cleanly and stop swarf clogging it.
-
Position the tool: hold the blade or edge to be sharpened flat against the stone at a consistent angle.
-
Work the edge: draw the tool across the stone in smooth, even strokes, keeping the angle steady throughout.
-
Check progress: inspect the edge regularly and repeat until it's sharp and free of burrs.
-
Finish up: wipe the tool and stone clean after use to keep the stone in good condition for next time.
