Oil and Knife maintenance

People use all kinds of things to lubricate folders. I currently use Tri-flow.
A product called "Nano-Oil" is recommended. People say the 85 wt is the best, the 10 wt is too watery and tends to go where you don't want it.

Another product is "Tuff glide". You can also get "Tuf cloth" to go with it. This is marketed as a lubricant, but its real virtue is corrosion protection. Use Nano-oil or Tri-flow on the pivot.
