SAK One handed Trailmaster. The one I took the serrations off of.

Got harder and harder to open. Figured THAT one out (I think)

Think I got whetstone dust in the joints and it was even cutting a pattern on the blade so pretty sure that was the culprit.

Seems to be between the saw and main blade which touch.

Oiled it. Got worse.

Let it sit in cleaning fluid (acetone) .....got ....fairly .....OKAY

Oiled it.....Got worse

Then got AWFUL.

Tried penetrating oil ....nope.....Tried SOAKING it overnight in penetrating oil.

NO DICE!

SLOSHED it in oil.....AWFUL.

Ran hot WATER over it. Worked GREAT!!!!!!

Oiled it.......needed a pry bar to open it.

Ran more hot water.......Worked GREAT!

Left it dry. Works great.

How? Wha? Where? How in the HECK could OIL make it bind up?

But it does. ANY oil. Tried Slick 50 that is supposedly sposed to leave a dry teflon coat and it is AWFUL.

But it works OK if I run ....hot water.......on it and then just let it dry.

???????????????????????????????

Theories????

:confused: :eek: :confused:
 
Try just heat, from a hair dryer, and see what happens,.
Also try WD 40 and see what happens.
 
Heres a theory- You haven't gotten all the particles out of it yet. When it is dry or wet with just water they stay out of the way better. When you oil it, they are lifted into bad places. Just a guess. What a weird problem.
 
Let's see...
Whetstone dust? From an oilstone?

If the dust is from an oilstone, it will be soluble in oil (and other petroleum products), but not water. The oil is dissolving the dust, and pulling it further into the joint. Because the oil also clings to the metal, the dust stays deep in the joint, partially wedged, and partialy glued by the oil. The acetone was partially effective because it dissolved the oil, but it didn't dislodge the particles because it was just sitting still. The hot water was effective because it was able to dislodge some of the particles, and wash away some of the oil.

Try soaking in solvent then flushing with water. Some dishwashing detergent added to the water won't hurt, and will help dissolve the oil.

fwiw, Rob

Man, I REALLY hate to see you going nuts and stressing over this, so just send the SAK to me as a gift, then you won't have to fret over it any-longer.:D.:D.

Just in-case you take me serious on this:

It seems fine running dry now. What think of having my jeweler buddy STEAM clean it?

:confused:
 
I put some Tuf Glide on a WH Monarch (not sure if it has any sort of washers), within minutes, the action was awful. Much like you described. I tried working the oil in by opening & closing hundreds of times, all to no avail. Finally, I squirted dishwashing detergent into the pivot and worked it in, then ran warm water over the pivot & rinsed thoroughly. Once the oil was washed away, it worked fine again.

The knife was fairly new, and was smooth as butter. Not sure why I felt the need to lube it, given that it didn't really need lubing. Moral of the story, don't fix it if it isnt broke.

NOt exactly the same as your situation, but thought I'd share anyway.

I have an Old Timer that's doing the same thing. Clip and sheepsfoot work great, but the spey is bound up terribly. I've tried everything from hot water to soap to oils, and I have found nothing that works. Even compressed air isn't pulling the grit out. :(
 
You might try using shaving creme to clean them out. Get Barbasol or some other kind that is foamy, my exprience has been that gels don't work. Anyway run hot sink water over the knife then put the shaving creme on it, let it get in the crevices for a few minutes then run the hot water over it to wash off the shaving creme and heat the metal. With the knife being hot from the water it helps dry it out. I've never used this on a knife but have used it on AR-15's lots of times and it does a really good job of cleaning dirt and oil out of the chamber. Sounds odd but it works on a rifle. :)
 
The jeweler has an item that will correct the problem, its an ultrasonic cleaner, its used to clean watches and jewelery. I used a much larger version in the AF and it flat cleans an item, I would imagine they use a nonreactive liquid in it. Ask.
 
I think smokinbasser may have just got a BINGO.

Either that or I should change this thread to say;

FIXED BLADE......FIXED BLADE......FIXED BLADE.

:D
 
Some polymer washers can expand when oils are used but not with water, that is just about the only thing I can think of, does not answer anything with metal washers.

Good grief!!! Get some WD-40 already!!!

1. Hose it down with WD-40, then dry it off thoroughly, using Q-tips and paper towels. This will get the gunk out.

2. Then wash the knife in the kitchen sink with some dish soap. This will get the all of the WD-40 and remaining gunk out. Dry the knife off afterward with fresh Q-tips and paper towels.

3. Then lube it up with some light oil.

These three steps work 99.999999% of the time with slipjoints. :)
 
Had the same problem with my NEW Case Wharnie, the action was very gritty. Cause was the polishing grits embeded in between the blade and liners. Used a high pressure car washer to blast between the blade and liners. Dried it up and tufglided and , smoooth....

See if the liners are alu, if they are, the grits might be stuck in the liners and the only option is to carefully blast high pressure water jet on the blade and into the liners to clean it out. Or you can dismantle it, but dont see how you can put it back as they are all force fit pins.
 
Ultrasonic cleaners are very effective.I used to own one.The good ones have a heat option.Jewelry solutions for precious metals and stones generally are amonia based.I'm not sure what the effect would be on certain handle materials.All metal knives would be safer to ultrasonic clean,or removing handle slabs.They do make ultrasonic solvents for guns and such.Maybe the Jeweler can help ya out.Good luck.
 
Took to jeweler. We ultrasonic'ed it AND steamed it. CLEEE-EEEANN !!!!
Tried to open. AAAAARRRRRGGHHH!
The Titanic's staterooms would open easier.
Took home. Ran hot water again.
A little better.
Dried it. DRY !!!

Got out my trusty old Marvel Mystery Oil. Just ....wet....the blade of my teensy SAK and used that as an applicator to the BIG SAK.

Now it's working. Not WONDERFUL.....but GOOD.

In pocket. Shutting up. Gonna cut stuff.

grrrrrrrr.

STILL some trace of black grit. grrrrrrrrrr.

May trade for Ginsu.

:eek: :D :( :mad: :rolleyes:
 
I am going to agree that there might be grit imbedded in the liners at the pivot and not enough gap to dislodge them. but there is almost always some clearance and one of the super thin feeler gauge blades might make it in and dislodge some perhaps or while wearing full face protection use high pressure air aimed at the "gap" if all else fails put some cutting oil in there and cycle the you know what out of it to reseat the moving parts.
 
The heat from the hot water may be causing the pin to expand or lenghten making it work easier. I would think the aluminum liners would also expand canceling this fenominom or as some one mentioned, the washers may be swelling with the various oils.

Or, your knife is posessed! :eek:
