Lockback Lubrication?

[Zemapeli]

As mentioned above, keep the knife clean or you risk gumming up the lock. I brush my knives with an old toothbrush every so often to keep the locking area clean, and then add a drop of blue lube. Light motor oil (or most any light oils) work fine too, I have used many different types of oil in the past. As stated above, I would avoid 3 in 1. I personally stay away from wd40 too, they both seem to attract dust and get sticky.

Rem-oil seems to do this too. Hoppes weathergaurd doesn't attract dust and works well for rust and lubricates fairly well.

After dry-toothbrushing the joint and lock area to remove dust and any chunks, I use Quick Release oil (often used on firearms), applied with a needle oiler.

If the knife has gotten really gummed up, a scrub with hot water and liquid dish detergent, followed by a thorough rinse, dry, and blow-out with canned air will precede the Quick Release.

Edit: I also have a small supply of wood coffee stirrers and popsicle sticks ("craft sticks") whose ends have been cut into points of various sizes and shapes to get into crevices deeper than a toothbrush can reach. By themselves, or wrapped in thin cloth, they do a great job of getting down into the blade well and cleaning it out.

You can give powdered graphite a try,that is what my step dad always used on his Buck 110. It can be found at locksmith shops and many other places.
