I actually just finished the little bottle I had in the knife box. I had great results, better than BM's blue lube. I had picked it up at Plaza Cutlery, so I guess it would be safe. However, I only had used it on my Emerson blades. I got some on the g10 and it came right off. Just don't spill it on your hands while putting the knife back together. It will get everywhere. So with that being said a little goes a long way. Also, I had used it on my Damascus Skyline's blade as a protectant and it still has not grown any rust or anything. Unlike the Blue lube I applied to the Damascus on my Scallion. So I would say it is pretty good stuff and would highly recommend it. Just not food safe.
