How does one disassemble needle nose pliers? Have a pair that is the worse case of frozen I've seen. Got it unfrozen using various commercial solvents for this, but still impossible to operate by hand. Takes an adjustable wrench on each handle to open and close (or an arbor press to close.

I have had good results with PB Blaster penetrant. May take several
applications but usually 2 or 3 times works for me. Getting old and
forgetting to put things up causes rusted joints to appear.
Be sure to apply to jaw, handle and sides.
