Francisp, Francisp....didn't I tell you to chuck that EZOut?
WD40 is not a preferred lube for knives. You should give the EZ a good washing with hot soap & water. use dishwashing liquid to break up and clean all the gunk that WD40 leaves. When it's all clean and dry, put in some White Lightening, or other qulity lube made especially for knives. WD is a great cleaner, de-ruster, not a good lube for tools. (PS: you put the lube in the "pivot" not the axis. Axis is a trademarked name for Benchmade locks)
Unless the blade actually comes out and locks open when you hold the handle steady, it's not a gravity knife. The EZ out actually has a staged opening, so it should offer some resistance to a pure "gravity" opening. Inertial opening (flicking)is sometthing else, and is not so clear cut, legally speaking.
Because I feel sorry for your EZout woes, and I think you really need to get a good knife into your hands to appreciate the difference...I'll repeat my earlier advice from a few weeks ago:
If you have $30 or so to spend on a knife, here's some free advice:
go over to
www.eknifeworks.com and pick up one of these:
Spyderco Calypso Jr.
Spydrco Rookie
Cold Steel El Lobo
SOG Mini Auto-clip
CRKT Point Guard
CRKT Crawford/Kasper
CRKT M16
Any one of these are superior knives to the EZout. The first 4 on the list are FAR, FAR superior knives. Hold any one of them in your hand and I guarantee you will find a nice old toolbox or glove compartment for your Gerber to retire to.
Good luck.
