As Mark says, it is often about balance. Sharpen your knife!
If there is an area on the tip that is either significantly thinner or thicker than the rest of the tip it can cause a section to vibrate separately from the rest, giving the buzz you describe.
Using a hard light and looking with both backlit and raked lighting, see if you can spot an area of unevenness in the tip?
I find that by feathering the whole tip with the lightest possible strokes, from blend to tip corner, in all four quadrants, can really even out the sound. One or two strokes in each quadrant, and crow, rinse and repeat. You will probably need to clip the tip up to pitch - all goodness. Sharpen your knife first!! This is really delicate work, but gives great results quickly.
REALLY light strokes. Remove only dust.
