Sharp reeds will happen because they are too short, too narrow, or too closed up.
Other than that, I cannot advise you because you have not said what kind of cane you are using, whether it is already gouged, shaped, and folded, what length you trim your reeds to, or what length staples you are using.
The problem with chirps almost universally comes from the area where the tip meets the heart. If the center of that location has too much cut away, the reed can chirp. When scraping tip, the best way to scrape is always with your knife at an angle, never parallel with the cut edge.
