Can someone help me with a good lube for knives with ball bearings such as the Spyderco Southard or the ZT 056X? I only ask because I usually use high speed pump oil, for my knives with washers, but I do not think it would work too well with these knives. I need something that will protect the balls from rusting, doesn't attract dirt and makes the flipping action smoother. Any suggestions? Your help is greatly appreciated.
