Sharpening the Tools
The Cameo-worker should always have a small oilstone at hand, and a few rapid strokes will restore the fine cutting edge of his tool, but the tool must be held the reverse way of working when applied to the oilstone. Hold the tool with the cutting edge downwards on the oilstone, at the same angle as a pen is held for writing, and move rapidly to and fro five or six times; this will restore the edge immediately.
