These days I'm using a paste car wax as a knife lube. I don't know what it's name is offhand. One day recently, I wanted to lube my knife and there was the tube of car wax, so on it went. It seems to work fine. I put it on with a toothpick or with the stick from a Q-tip. I figure it won't attract dust and grit the way oil will.
I've used various lubes over the years, on my knives and on other things such as my bicycles. I've never used Militec, and it sounds like a good product, but isn't it kind of overkill for something as nondemanding as a knife lube? I mean, a knife hardly puts the same demands on a lubricant as does a gun or an gasoline engine.
