The ideal tool for removing blocked buttons or for holding the button securely when sharpening. Suitable for violin and viola buttons, also for buttons with pin.

N.B.: given the processing with numerical control machines, it is advisable to remove the burr from the edges before use. Furthermore, sometimes it may happen that a button does not enter comfortably depending on the model. Being in soft metal you can easily file the edges of the extractor with files or sandpaper to adapt the entrance to the button.
