Hello fellow microholics. The pivot on my UMS has loosed up, and I need to find a wrench to tighten it up. Do you guys know where I can buy one?  I do see that Blade HQ has an “extra large” size available, but I’m not sure if it’s the correct size. 

Thanks for the help 

-Ben

Description says span from the pins is 0.155” and pin size is 0.055”, and that’s what I’m measuring on my pivot.

thank you for the measurement pics and I've been trying to track down a UMS pivot for some time. I asked PVK and they said the have a 4.9mm that will "probably work." I didn't order it as I was not convinced. I have a few bits coming and one may work on the UMS pivot. If so I will be sure to take measurements and pics so you know (at least) what to look for. This has been a difficult bit to track down

I will add that I ordered the extra large bit from BladeHQ and it did NOT work

Yikes I’m confused haha. You did order the extra large and it did NOT fit your UMS pivot? The specs I quoted were from blade hq’s XL that’s currently available. Seems correct?

I got a simlar response from blade hq. They said they aren’t positive what will fit, but said they would be happy to return the tool if it doesn’t fit.

This is the one I ordered, it was domed so maybe that's why it didn't fit, but it definitely did not fit. Please keep me posted on your quest. PS: I never bothered returning it to them but was told I could if it didn't fit. Also worth mentioning that I have a caliper and tried to measure it but it's not digital and in inches... I'm rusty when it gets small and non metric

Dang that’s the one I was going to order! Haha.  Glad I posted this, you save me the wasted effort. 

The quest continues. I’ll keep you updated. I’m getting something shipped to me from PVK soon, so I’ll try the one they have.

Ps, kind of hard to tell in my pictures, but I definitely have a domed pivot.

You need Part #00130 for the pivot screw.
Part #00120 for the handle screws
I have done business with this guy twice and has always been good.
If your still not sure read the paragraph below the size chart about sending a picture of the knife with a dime on it.
