The lightweight FELCO 903 sharpening stone in hardened steel is perfect to restore the damage on any unfortunate cutting edge. The diamond coating means it is extremely strong, which not only reduces wear and tear but gives the stone a longer life, which in turn extends the quality of your cutting tools. Sharpen, deburr and hone your tools to a standard that will impress any professional. Overworked pruning shears, cable cutters and loppers will be transformed when their blades are held at the correct angle in relation to the FELCO 903. Just applying slight pressure puts shiny and sharp back into your pruning work and life into your tools. See product instruction cards or online for the correct sharpening angles and techniques.
