560CBCF - squeak

[sticktodrum]

Best course of action is to clean the blade and frame lock if you can take it apart. If it still squeaks then apply a small amount of lubricant to the travel path of the detent ball.

If you don't feel comfortable opening it, then send it to kershaw.

Best course of action, as illustrated above by the OP's response, is to leave it alone and let it work itself out.
