I just cleaned, sharpened, and oiled a friends 720s. It was the first time I'd ever really handled an axis lock besides quickly checking out a 705 once. The 705 was awkward, but I kind of liked the 720.
Anyhow, it hadn't had any maintnance for a while and was all gummed up getting stiff.
To clean it, I loosened the pivot pin until there was a good deal of side to side play in the blade. Then I Gave it a good blast of WD40. After that soaked for a few seconds I blasted it out with an air compressor until no WD40 was blowing out anymore. I did all that twice and it took all the grit out of the action of the blade and axis bar.
Then to oil it, I left the pivot screw loose, and and used a needle oiler to shoot a little oil down ontop of the tang at the axis bar. Working the blade a little let it run straight into and around the pivot. I tried using a heavy oil since the knife is so open. I figured it would last longer because it wouldn't evaporate so easily. I think it was a single weight, synthetic oil. Most likely 30 weight. I can't say for sure because I don't remember what I used to fill the oiler up last time
Once everythng was clean and oiled, I tightened up the pivot until there was absolutely no side to side play in the blade. When I pulled back on the axis bar the blade dropped closed from its own weight. Very smooth
The whole process took about 5 minutes. Sharpening was a different story though
