Dr. Marv's Wunderlubrikant is the honing oil Dr. Marv uses for most of his published stone reviews, developed with the German lubricant maker Oelheld GmbH.
Why it's different
- An ester-based, high-tech MQL (minimum quantity lubrication) oil
- Non-hazardous, and it rinses off with water without leaving residue, so no solvents are needed
- In Dr. Marv's months-long exposure test, it caused no damage or breakdown to resin bonds
How to use
Apply a good layer to the stone before sharpening and add more if the surface starts to dry out.
Pairs with
Dr. Marv's coarse, medium and fine resin-bond diamond stone sets.
From Dr. Marv Himself
“Lubrication is of utmost importance for a long lifetime on the abrasive, but
also the result.”
Looking around, the typical products used mostly focus on reducing
“loading” on the stone. The idea being that a clean stone cuts best. I
seldom find information about the actual performance of a lubricant in
terms of enabling a perfect cut – just what we need for the best possible
sharpening action!
The 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.
In 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
tendency of resin stones to load to be at least one order ofmagnitude lower
than with the common mineral oils. Lastly, to enable aclean cutting action and low wear of the diamond grain, the ester-derived“Wunderlubrikant” is
wonderful at lubrication.
When 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”. Thank you!
