DIY Frequently Asked Questions / Sharpening Stone')">
Available in diamond, oiled and dry models, these tools are used to sharpen various blades of cutting tools.
Diamond whetstones sharpen using the diamond dust from the stone.
Oil stones must be oiled to avoid accumulation of the metal particles from the tools being sharpened. To oil the stone, put a drop or two or lightweight household oil on the stone before each use. Also, new stones should be soaked in a bath of oil for several days before use.
Flat whetstones are the most common type of oil stones with both a smooth side and a coarse side for various sharpening requirements.
Drystones wear out much faster than oil stones because the stone’s surface crumbles away when sharpening.
Be sure to study manufacturer literature to recommend proper stones for different types of blades.
