The blades are seized despite copious amounts of WD40. Blade locking screws are not over tightened. Despite removing all screws, unable to remove plastic housing in order to inspect further. Any help would be greatly appreciated!

one of the screws in the housing has a middle section in the head part of the screw, you can overcome this by using a small flat bladed screwfriver to undo or simply drill out with a small drill bit, tip when you open the handle casing see if you can see the trigger mechanism which way the spring is located as i made that mistake let me know when done
