I Only Use the CRK Grease. I have found it to work perfectly. Since it works so good, I have found no need to even try anything else. Chris is the master, if he came up with it and puts his name on it, he feels its the best for his knives. I am sure Chris tried all the others out there before settling on this. The tube it comes in is great and is very easy to apply where you want it. :thumbup::thumbup:
