ASSEMBLY OF THE DEVICE
The device must be securely attached to the base (E) – it has openings in the bottom
intended for screws (not included). After attaching the device to the base, fit the
appropriate attachment (B or C or D) to the whetstone, depending on what you
want to sharpen. The remaining attachments can be installed on the sides of the
device – see images below.
