The tool dulls rapidly, but the steel is soft enough to easily sharpen. However, the corners of the tool round (instead of remaining crisp) so fast I need to re-grind after each use. That is, using the tool to cut a 6" bowl's base down to 3" means I cannot use waterstones to sharpen but, instead, have to employ a grindstone to return sharp corners.
Pinnacle Diamond Parting Tool.
The diamond parting tool sharpens with little effort, but that is because the steel is soft enough to become dulled rapidly. While the product description talks about temperature altering the metal characterisitics, in reality the tool loses its edge quite rapidly. The good news is the steel is soft and easily sharpened.
