FAQ, Hints & Tips

Bedding In
All new diamond stones from any manufacturer will feel very coarse to the touch regardless of the micron or grit size of the diamond. This is quite normal and after the first couple of times being used, the stone will bed in and the difference in grit can be noted by touch alone. However there’s a grit number on it just to confirm what you thought.

No Pressure
An easy light pressured sharpening stroke is all that is required to gain optimal abrasion rates from any stone in the Diamond Cross range. Excessive pressure is not recommended as it can literally tear the diamond particles from the nickel plated bed.

We recommend using our unique fully synthetic lubricant.

Dangerous Tools
Warning all the tools mentioned in the above text are very dangerous in the hands of the young, inexperienced or untrained. We highly recommend only experienced users attempt to sharpen tools.
