    Hello everyone. I did a couple searches and couldn't find anything, so I hope that this hasn't been discussed to death.

    I have a Mcnees Baby Bolt that I love, but recently a buddy of mine flubbed the flip a couple times and when he handed it back to me there was some grit. I thought that it was strange so I ran a paper towel across the detent track and it smoothed back up... For like 5 flips. Now every few flips it grits up and I have to clean the detent path.

    Ideas on how to fix this? It's driving me insane.

    I've had detents go "gritty" completely at random on five or six knives before. I think backlocks go through the same phaze sometimes too. Sometimes it's bad enough that I give up and shelve the knife for a few months, sometimes it's better when I come back, sometimes not. I've tried polishing the detent, no dice. Tuff Glide only seems to help momentarily. It always seems to go away eventually though, I've never read an explanation for why it happens.

    Is it a relatively newer knife?

    It is like a year old. It's been carried quite a bit and has been as smooth as glass since I got it. The ball looks fine (as far as I can tell) and the track doesn't look noticeably different than any other.

    Joshua J, I was considering polishing so it's good to know that I'm probably better off leaving it be.

    I tried a drop of lube and it worked for a minute and then roughed back up. Scratching my head on this one and getting pretty irritated, ha.

    Thanks for the replies fellas.

    Just needs cleaned (flushed out) in all likelihood.

    I would agree. Pocket lint and lube/oil can build up and it probably just needs a good thorough cleaning

    Toothbrush! Just use it to brush out the pivot area, detent track, and I make sure to brush the actual detent ball too (on liner and frame locks).

    I will spray the bristles with CLP every now and then to keep them a little oily. Not dripping with oil but a very thin coating. Seems to help clean the detent track better and "refreshes" the lube on it.
