Problem with new slip joint

Hi,

I just had an inexpensive slip joint come in and it's not opening or closing right.

The heel grinds when the blade moves. There is no snap, and i mean NONE, when the blade is pulled into it's final open position or pushed into its closed position.

It just doesn't snap into place, even the final inch or so. Again, it must be pushed or pulled all the way to close or open.

There is some file work. The blade is centered. I oiled the hell out of it hoping some metal might get freed up and fall out.

Other than the attached pics, these are the best clues i can offer. What do you think the problem is?

Thanks

Sounds like the joint may be too tight (assuming it was sprung correctly to begin with).
Is there any blade play? If not, try this: You can slacken it a bit by pulling the blade side to side when open. Not too much, just enough.
 
Try spraying the heck out of the joint with WD-40, scrub with an old toothbrush, spray again, see if any gunk comes out.
can also try spraying and working the blade some after the scrub.
Sounds like there may be some crud in the joint.
 
If you are willing to do some work to it then make a wooden wedge that you can use to tap down between the liners so that you can try to pry it apart. . It should not take too much to get some clearance between the liners and the blade. Tap Lightly too !!! Do not Hit it !!!

Before taking more extreme steps, I would wash it in the sink under running water and use dish soap. Then rinse it clean in water, then in rubbing alcohol, blow dry it, rinse it with WD40, then apply some oil. Just to make absolutely certain that there are no chips are still jammed in there. In your closeup pictures, it appears to me as if there are little trails like as if some grit was still there. I find the soap and water treatment to be more effective than just running oil or WD40 through it.

Fellas,

I followed all the suggestions i was given and the heel grinding got better and better. Then i followed the above instructions and all is well. Opening and closing the knife is now perfect and it clicks into place upon opening and snaps closed with a loug snap.

Thank you all.

If you look at the picture of the opened knife in the first post you'll see it has no thumbnail groove in the blade to make opening it easier.

Is there a way to add a groove to the blade and if there is, how is it done?

Thanks again.
 
I would think a dremel with the "disc" attachment should work. I've cut into s30v steel fairly easily with one. Just remember to go EXTRA slow so you don't over heat the blade.
