Sirgrumpsalot,
The best lube that I've found,is plain old Duralube. It inpregnates the surfaces of the metals, so the knives are very,"walkable", even when very "dry",and a container will last almost a lifetime. I haven't used 1/4 of mine yet,on all my carry folders or my whole collection, and its been 6 years.If I find something better all I have to do ,is put the rest of it in my car!!! Nothing wasted!
