I'm in the process of disassembling a PM2, and I have run into a hitch. The pivot screw does not seem to want to come loose. I'm using a T8 torx driver on it, which fits well enough... its just that it won't budge. Does spyderco use loctite on their pivots? If so, what would be the best way to go about breaking the seal?
 
Heat up the tip of a screwdriver and touch the pivot screw with it to transfer heat, repeat as necessary until you can loosen it with your torx driver.
 
I got a t9 screwdriver and I tried heating the tip of it, but it was to no avail. Also tried submerging the pivot in boiling water; that didn't work either. I actually ended up partially stripping one of the screws, so I'm pretty pissed. Any other ideas?
 
Hmm... that could work, but I figure I'll just leave it as is. I don't want to muck it up any further.
 
have you tried a power drill? i couldnt do it by hand and then i tried that and it worked no problem. that might help... just be careful not to strip the screw

Simultaneously?

No, just one side at a time.

I don't know about the PM2 pivot, but for my Chaparral, one side is actually the female end of the screw that is not supposed to turn. The female end is a semi-circular tube that prevents spinning when the actual screw is turned.

See picture below:

I don't know why, but for some knives, a torx pattern is cut into the female end, and that's really misleading.
 
In that case, I have tried both sides. If it does happen to be that type of pivot, then there's a 50% chance that I'm already screwed, b/c I've already ruined one end.

:D :p

On a serious note, my way of dealing with Loctite is with a soldering iron. Hold the hot tip in the screw head for ~30 seconds, then slowly turn the screw with a screwdriver.
 
I ran into the same issue trying to loosen the pivot on the PM2. I clamped a pair of vise grips onto the handle of my torx screwdriver that gave me the extra leverage to loosen the screw. This is probably not the optimal method and I have ruined things in the past using the brute force method of disassembly, but luckily I did not damage the knife.

This is what I do as well. A little heat will soften it up enough to loosen. And you have to use two torx drivers - one on each side.

stick the folding area of the knife under hot water worked for me, left it there for 30 seconds. The screw wouldnt budge before
