Some of my EDC 110's are very hard to press to unlock. Any suggestions on how to "soften" them up?
The blade rotates smoothly and with proper resistence; the unlock spring is very resistant or hard to press far enough to release the lock bar.
Thank You, hill1096
 
Hill, Welcome. I've seen this once. Sometimes it improves with use and put some lubricant in the blade well where the spring engages the lockbar and at the blade pivot. DM
 
I've had this happen when the knife becomes fouled with junk. Buck 110 + sand = :(

My solution based on input from others... Wash thoroughly with lots of dish soap and hot running water while operating the knife to clean out everything. Flush with your favorite water displacer (WD-40 or CRC 6-56) and then use lubricant of choice.
 
I find it easier to close a 110 with the side of my thumb, seems like most I`ve seen close use their tip. Perhaps this will help.
 
It sounds to me like you are describing a tight lock to tang cutout fit. Is it hard to press the lockbar down, or is what you are feeling a slight hesitation of the blade rotation to closed when the lockbar is depressed. A good flushing out with some liquid dish soap then running water while working the lock and blade a bit, followed by a blast of canned air, or compressed if you have a compressor, then some wd40 might help. Working it a bunch might help to wear it in a bit as well.
I wouldn't leave it half open, that might just weaken the spring and not address the root problem...
Of course a trip to post falls might be in order as well, let us know how you make out.
 
I go with sit and pinnah. Dish soap, old tooth brush, long bristle brush and lots of hot water. Let the water run through the knife and hold the lock bar down to allow the water to flow between the lock bar and blade. When you dry it out with air do the same and shoot the air in the same area.
 
You may have already cleaned the knife, but another trick I do while using the Dawn dish liquid and hot water is to hold a finger partially over the water faucet to create some high pressure jets to spray into the mechanism. Better yet to have a second person create the faucet jets while you work the blade back and forth.

UPDATE
I took 8 of my 110's ( 4 workers,2 retirees, and 1 new and 1 barely used ) outside and one at a time pressure washed with brake kleen and then thourghly cleaned and dried with air pressure with a fine tip and 40 psi max.
All 8 are markedly improved and 4 are dramatically improved.
I finished up by lubeing all 8 with nano-oil.

Thanx for the update hill, I see that I hadn't fully read your original post...My Bad!
But have found on many occasions that a thorough cleaning and a good blast of pressurized air and a lube will make these 110's and 112's really sing their song :)
