Last week my paradigm locked up in the open position , I was eventually able to free it up , then it locked in the closed position. I was able to get it working again by just moving the bolster back and forth afew times . however my success was shortlived as it finally stopped working altogether. I was tempted to disassemble it but decided the best thing to do was to send it back to buck for repair. I'm just curious has anyone else had aproblem with their paradigm?
