Brought all of my pics back and now they are here on MTO and PB can't mess with them now

I'd be inclined to soak the Supertool in very hot water with dish soap, leave it for a while to soften the oil that will doubtless have solidified over the years. Then begin to slowly work the tools open in the hot water. Turn the oven on high . remove the tool and pour boiling water from a kettle over it.. Pat it dry with a soft cloth, place on a baking tray and shove it in the oven for half hour.. Remove, allow to cool and soak with copious amounts of WD40.

It's what I always do and has never let me down nor caused rust issues.

Yes really
If you use wd40 as the tool comes out of the oven it discolours the steel to a goldish colour, I know because I did so on a incredibly stiff tti I purchased years back.

The BO flik I got a few weeks back was stiff and I did exactly the above. Silky smooth now

I ask because I use my oven for everything from drying work boots (below 50oc) to heat treating carbon steel (220oc)
my oven will go 250oc+
Are you sure you are not ruining the temper on the tools? softening them? or making your blade brittle by heating then quenching it with WD40?
