I have enjoyed all of my Tesoros, but only ONE has never had shaft creak, and I suspect that's due to the sand that's gotten in the shaft joints. That's the Tiger Shark. But the uMaxe's I have and have had, have developed an annoying "creaking" sound when swinging. This sometimes is right out of the box new. If you over-tighten the plastic shaft locks, they will break(snapping-sound) internally, and then you're worse-off than you were before. That is the ONLY complaint or problem that I've ever had with a Tesoro. Any quick-fix suggestions? Thanks..
