Black Fox Feresa Disassembly

[Aerosmith101]

I got my sister a Black Fox Feresa a couple of months ago and I tried to disassemble it to clean it up but the pivot screw won't budge, I've tried using a soldering iron and I tried gently tapping it with a small hammer but it still won't budge. Anyone have any ideas on how to loosen it up?

You don't have to disassemble a knife to clean it.
The screws are for assembly, not disassembly.
