Impossible pivot...

[birdave]

When I get a knife I tear it down, clean it, re-lube everything and sharpen the blade, if necessary.
I just bought a Occam OC-1, but no matter what I've tried, I can't free up the pivot.
One side is a T-8 bit fastener and the other side is flush with the frame.
I can't get enough purchase on the side of the pivot that's flush, to loosen the T-8...both sides of the pivot turn simultaneously.

Any ideas?
Thanks in advance to all for their suggestions.

Basically you gotta have the knife fully open and you want to keep applying side pressure on the blade so it seizes the pivot while you loosen it.
Maybe tape up the blade and put it in the vice and then apply sideways force on handle (start bending the knife) and unscrew at the same time. I loosened a knife with similar issue just by laying it flat and applying downwards pressure on blade and handle, so up to you, be careful, good luck.

Thanks for weighing in , I 'll give it a try. Much appreciated.

Can also try turning a computer mouse pad upside down so the tacky side is up. Lay the knife with the blade open (best to tape the edge so you don’t cut yourself), and apply a lot of pressure as you unscrew.

This has a little of the side pressure as said above, and the tackiness of the mousepad will help hold that pivot also. I’ve had intermittent success with this.

Also consider that there may be loc tite, which can sometimes be broken with a sharp whack to the bit driver while it’s in the head. Heat from a soldering iron until the opposite side is too hot to touch has worked more often for me though.

Good luck, this issue has driven me mad in the past.

If you have reason to believe loc-tite has been applied to the pivot, heat (from a heat gun) can help.
It's always worked for me.

Gentlemen,
Thanks Very Much for weighing in with your suggestions. I tried the mouse pad, hammer whacking and the pressure on the blade...It worked!
When I tried to loosen it yesterday, I whacked it with a hammer (the bit) a few times, but apparently not hard enough or not as many times as needed. Apparently, the mouse pad gave me just enough hold, to make it work. I tried rubber and a couple other things yesterday, but no luck.
I thought I would see Loctite, or a lot of rust, but all I saw was VERY little rust on a couple of spots on the blade where the pivot goes through. So little that I was surprised. The knife is in New condition, so I couldn't understand what made the pivot so hard to loosen. I've never had a pivot give me this much trouble before and I've taken A LOT of knives apart.

Once again, I sincerely than you guys for your advice, Truly appreciated!
Have a good weekend and stay safe.
