The idea being that a clean stone cuts best. I\u003cbr\u003eseldom find information about the actual performance of a lubricant in\u003cbr\u003eterms of enabling a perfect cut – just what we need for the best possible\u003cbr\u003esharpening action!\u003c\/p\u003e\n\u003cp\u003eThe product you are looking at is my answer to both – it is a high-tech the oil film does not drip off the stone, but is still thin enough to quicklycoat the stone, the blade and reach into the pores of the abrasive. Theproduct you are looking at is therefore carefully selected for it’s viscosityof 10 mm²\/s.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eIn order to avoid loading of the stone but also supply continued lubrication down to the grain-metal interface during the sharpening action, the oil needs to have proper load-bearing capacity. For this reason, I selected an oil designed for stamp and die processes. I personally found the\u003cbr\u003etendency of resin stones to load to be at least one order ofmagnitude lower\u003cbr\u003ethan with the common mineral oils. Lastly, to enable aclean cutting action and low wear of the diamond grain, the ester-derived“Wunderlubrikant” is\u003cbr\u003ewonderful at lubrication.\u003c\/p\u003e\n\u003cp\u003eWhen I set out to develop my sharpening stones, I didn’t see myself everselling oil. The regulations in Germany are very strict, and shipping is quitefrankly a nightmare. This product is only possible because of thewonderful people at oelheld GmbH, a German specialist producer forgrinding, cutting and lapping oils. I am in their debt for their gracioussupport in realizing “Dr. Marv’s Wunderlubrikant”.
