Advice needed on budget knife selection

Good choices there, you should get on well with them all as long as you like the Axis lock.

Nice knives - have all (only the 720 is missing). The EL02B is one of my all times favorite (stonewashed blade finish, good axislock - the screw is a little bit sharper (you will notice this on the thumb) as the Ganzo one, but who cares? You don't open the knife 20 times in 2 minutes).

today i received my order of enlan el-01B and ganzo g620-y1.
i ordered them from fasttech 1 May, and today 12 May i received them, that’s really fast by my measures!
i’ve never used a spring assisted knife before, so i like the ganzo.
the enlan seem to be a quite sturdy knife, so i’m sure it’ll be good company for many years to come!
can i use teflon lubricant spray on the knives to loosen them up on opening?

My folding knives:

$1 knife from wallbuys IIRC; SR Columbia
Appalachian trail (from an O-L christmas giveaway)
Ganzo G620-Y1
Enlan EL-01B
