Ran out of WD40 which I normall to lube my lansky kit stones when doing a quick sharpening. Used what I had on hand just out of chance and it is contact cleaner and lubricant from radio shack. Stuff is kind of hard not to make it go all over the place when spraying it on your hones but it works the BEST of anything I have found to date. Keeps the stones nice and clean helps it cut like crazy. I am now the owner of the sharpest CQC11 on the planet bar none. Just passing along what I found out by accident or serendipitously. keepem sharp:thumbup:
