Mcusta Pivot Spins when trying to adjust

[Fred Sanford]

Hey folks,

Anyone have any insight to this? One side is a flat head screw and the other side is a blank. It just spins and spins and spins. I cannot put enough pressure on it with my thumb to prevent it from spinning.

Only thing I can think of is something really tacky like a piece of something rubbery that I can press into the blind side of the pivot while I tighten the other side. Any thoughts?

I love the knife, but need to tighten the pivot a bit.

There's probably loctite on it as well and you'll need to heat it up to remove that. maybe dunk it in boiling water.

What kind of lock is it? With some types at least (perhaps all--dunno), opening it will put pressure on the pivot pin, which can be enough to keep it from spinning.

It's a MCusta Gentleman's knife. It's a small liner lock.

Good thought about the pressure on the pivot. I'm going to try to squeeze the knife blade (while shut) so that it puts shear pressure on the pivot pin and see if I can adjust it that way.

 

[Fred Sanford]

Well that didn't work. Good thought though.

David,
What I do is flick the blade open and lay the blade flat on the workbench with the handle extending beyond the edge or the bench. Then apply some pressure on the handle like you were trying to fold the knife in half sideways. This will bind the pivot so that you can either screw or unscrew the pivot.
Be careful though and don't apply too much pressure. It may be to your advantage to wrap the blade in a towel or put duct tape over the blade edge before you start applying pressure.

One of the Kershaw people recommended opening the knife and putting pressure on the edge, as if you were cutting into something, like a hard table (this was for the Avalanche model which has a similar spinning pivot). As you are applying pressure with one hand on the knife handle, use the other hand to unscrew. Very similar to what Veil said, only edge on the table rather than sideways. (one of the two should work)

Thanks guys. I'll try it and post back with results.

Another option, assuming it isn't pinned, is take the body screws out and increase the gap between them at the butt end--same idea as using pressure from the blade to hold the pivot in place but with the handle slabs doing the work instead

Thanks to you all. I did exactly what Veil said and it worked. Removed the screw, put some new Loc-tite on it and then put it back in and tightened to my liking. It took a bit of messing with to make sure when it was all done the blade was still centered but it all worked out. Took less than 10 minutes and now this Mcusta is "my" knife.

Much appreciated! :thumbup:

This worked like magic and only took a few seconds.
