Recently picked up a Case Medium Stockman. I've noticed that the clip blade has little tiny bits of metal/sand/grit in it which makes opening and closing the knife INCREDIBLY difficult. There is so much grit that I can hear it grinding as the blade opens and closes. It's very strange seeing as how I can clean it out when the blade is closed, but when I open it again, more grit appears. I'm not sure what it is at all nor if it is normal. If you've ever played around with a magnet and iron filings, that's what it looks like. They are definitely magnetized and stick to the blade like iron filings do to a magnet. Does anyone have any idea what is going on or how to completely clean it? The strange thing is the sheepsfoot and pen blades are perfectly fine...
 
Upon further inspection, there is definitely some kind of grinding going on between the blade and lock. As I close the blade I can actually see the filings forming around the edges of the tang of the blade. Any help is appreciated.
 
More inspection....with the proper light and angle, I can actually see metal shavings falling if I continuously open and close the blade. I guess technically when enough shaves away it will stop rubbing but somehow I don't think this is supposed to happen in the first place....
 
That is normal with new knives. There might be some metal particles or polishing grit that is stuck between the blade and the liners. Nothing at all to worry about. Just oil the joint and work the action a few dozen times. You'll see the grit come out with the oil. Wipe it off and repeat as needed, and when you're done the walk and talk will have improved.
 
Thanks, I'll oil it up as soon as I get home. I figured it wouldn't be a serious problem.
 
Any new knife of mine gets a good scrub out in hot soapy water using a tooth-brush,then a proper drying and some oil. That seems to work wonders, don't drop the knife though.....
 
I like to use the straw on a can of WD-40 to blast out the grit. Then dry it and re-oil it with 3-in-1 or Ballistol.
 
I use Breakfree CLP and all that junk will come out as a black film. I keep working the action and cleaning off the black stuff until it stops and the action feels smooth.
