Geissele is one of the most precision oriented companies in the firearms industry, and they have the highest quality machining of just about any company out there. Best triggers and optics mounts on the market. Nothing they do is half assed, so if there's one guy I can trust the integrity of its him. In the video, I believe he explains the process in which they tested it and came up with it, I think he said he only developed it because they used it for a stress test machine that needs very high-end lubrication for thousands upon thousands of repetitions. It is non-toxic, but food safe I'm not quite sure so I'm cautious. I like the grease in particular because it's a quadruple zero rated grease it is very thin but stays in place very nicely. Since it's for guns you get a decent amount for the price, it would last you forever in regards to Knives
