All cutting edges are very sharp and care must be taken to prevent injury.



Diamond Cross stones allow fast, clean stock removal,with less effort and time required and can be used on a variety of cutting edges.

When using Diamond Cross stones, certain general guidelines should be followed to ensure that the stone will give lasting performance under normal conditions.

Follow the hints and tips explained here to help maximise the life of your Diamond Cross Stone:

  • All tooling should be cleaned before sharpening. Resin build-up should be removed with Resin Cleaner and a wire brush.
  • Use with Diamond Abrasive Lapping Fluid (water can be used if necessary), this will prevent the diamonds becoming clogged with swarf.
  • Diamond Cross Stones require a ‘break-in’ period. Initially the diamond will feel coarse and will smooth overtime.
  • Do not apply too much pressure.
  • The diamond is extremely abrasive so what would normally take 5-10 minutes on an oilstone may take approximately 20 seconds on the Diamond stone.
  • Dry the Diamond Cross stone thoroughly after use. Any wet steel filings left on the stone will cause surface rust to form.
