A Case of neglect?

[Vicarious Reality]

I got myself a 4'' yellow CV slimline trapper from Case, and after having opened and closed it for a few hours, it suddenly started grinding metal at the pivot at the lockbar.
I guess i should have oiled it more?

That's not normal, there's propably some sand or dirt in there? Have you tried opening/closing it under hot water and oiling it up?

That's just my amateur advice.

Umm...yeah that sounds wrong. Try cleaning out the pivot and see if that fixes it.

clean it well, done it to a friend's soddie and it worked, clean with soap, paper, brush if available and then oil

I rinsed it under the faucet... still feels about the same.
It doesn't work as good as it used to... it sticks when i open&close it.
The tang looks like crap, all scarred and uneven. I really don't have any tools to deal with this.
I guess i'll just have to buy a new one and try to keep oil in it and sand out of it.

I've seen this a couple times myself. Someone put the wrong oil on a new knife and it never went back to normal. Someone polished the brass on a Buck 110 with steel wool and the steel got into the pivot. It never went back to normal.

As I'm not that great of a craftsman, my approach was to put molybdenum grease (e.g., the smelly black stuff for car CV joints they sell at auto parts stores) on the pivot pin. It helped but not 100%.

If you have the skills to disassemble it properly you might be able to smooth the pivot pin, but otherwise you are likely to get it apart and then never get it back together.
