I have a yellow delrin case cv trapper that i got after christmas and i love it to death BUT in the last day or two it has developed a gritty action in the clip blade that is making it hard to open. This was ok till about 10 min ago i took a chunk out of my thumb because of the gritty action.

Is there any way to fix a gritty action on a case slipjoint? It will probably affect if i carry it because the clip blade is becoming a pain in the a$$ to open, while the spey opens pefectly.
 
Well... use some handwarm water and soap and open and close the knife several times. When the "gritty action" gets a little lighter, I would use some mineral oil inside the springs. Then open and close it sometimes again.

If you have an ultrasound-cleaner at hand you could use the cleaner with some handwarm water and soap - that works pretty well (for me).

From my part of the world ... handwarm water & soap and some mineral oil will work.

I hope that helps a little...
 
I use wd40 with the straw nozzle to blow gunk out of the joint. Then I lube the joint with 3 in 1 oil or ballistol.

As much as I like Ballistol (it´s made in Bavaria) - I wouldn´t use it on a knife with brass liners. It is made as a weapon oil and will eventually "attack" the brass on the liner because inside the barrell of the rifle there will be some rests of the brass of the catridge. Ballistol is made to remove it. It could (!) attack the brass liner.

WD40 might work well, imo.

Just my thoughts and heard experience.
 
Flush it out with oil/wd 40 and work the action. Repeat until it the action is clean, then wipe the knife down.

I have done a hot soap and water scrub when that did not work (using a bristle cleaner to clean out the action). Dry with a hair dryer or other hot air source (shop vac will work for that), and then oil the joints.
 
Thank you guys so much, im new to traditionals so i didnt think to oil it with wd 40 or 3 in 1. The second i put wd 40 on it it became as good as new. Just as a precaution i used 3 in 1 also and now its smoother than when it was new.
 
The 'black gunk' is, unfortunately, all-too-common in new Case knives from the factory. I think it's leftover from the buffing/polishing done just before the knife gets packaged & shipped.

1. WD-40 flush (don't be shy with it). Work the joints while doing so, to dislodge as much of the grit as possible.
2. Let it finish dripping out, then give it a bath in hot water, at whatever temp your hands can tolerate, plus dish detergent like Dawn/Ivory/Palmolive/etc. Again, work the joints (be careful, the knife will be slippery).
3. Rinse thoroughly in hot water, again working the joints.
4. Dry everything thoroughly. This is where the hot water wash/rinse helps, as the knife should be very warm at this point, and residual moisture will evaporate very quickly.
5. Use a little WD-40 in the joints again (sparingly), just to displace any residual moisture that might still be in there.
6. Lube the knife with your oil/lube of preference.

I have used mineral oil along with a can of compressed air.like you use to clean a computer keyboard. Also I have over 250 carbon bladed knives and have used Ballistol for a long time with no adverse affects.
 
id be curious to know if you resolved the problem? the fine gents above posted very sound (tried and true) information. by the way, the blood makes it look a lot worse than it is :D
 
Wd-40 then blow it out with an air nozzle if you have an air compressor. That's what I've seen a lot of people do and done myself.
