As a long-time FolStaf user, I've found sticking of the sections to be only a minor problem and I've never had the sections pull apart. I don't like the idea of banging it against a rock to aid disassembly; that sounds like a recipe for current or future damage. When the sections do resist coming apart I've found that pressing the joint against my knee, then rotating the shaft 180 degrees to do the same thing at the opposite side will release the joint every time without resorting to forceful measures.
