The diameter of the screw that holds the handle together at the pivot is 0.085". That means the cross sectional area of the screw is 0.0057 square inches. If the tensile strength of the alloy used in the screw is 30,000 pounds per square inch, the pivot screw can stand 171 pounds of force. That is assuming the screw is loose enough to have no pre-load on it, which is seldom the case. When you start twisting or prying, the torque you apply tries to force the handle sides apart, applying addition tensile load to the screws. Because of the leverage involved in the various parts, the amount of torque you apply will be multiplied several times. It doesn't take a gorilla to apply a couple hundred pounds of force to the pivot screw that way.
If you want to twist and pry, stick with a full-tang fixed blade.
I don't believe in safe queens, only in pre-need replacements.
