We've lived with a Martel two bladed folding prop forever. Occasionally one blade will not open but putting it in reverse and back into forward has always worked for us. Each time we haul out (once every two or three years here in the Northwest) we remove the blades and thoroughly clean and polish all the parts. Maybe that helps. We also apply a little grease to the moving parts but I'm not sure that makes any difference. If I were having your problem I would look closely at the surfaces that move against each other to be sure there are no burrs which might cause the blades to hang up against each other. Dave.
