The bit in the photo is a handsaw
medallion countersink bit used to bore the hole for the
installation of the brass medallion on the left side of handsaw
As you can see, this bit is very specialized
in its design.
The bit bored a recess for the
shank of the medallion nut which is larger than the other nuts
on a saw and then bored a recess for the decorative medallion.
This specimen is probably late 18th Century in origin and is
stamped, in small letters, "NAIRNS".
This is of the back of the saw medallion bit,
the side opposite
the spurs and floor lips.
Although in my research I have seen
illustrations of saw medallion bits this is the only specimen of
one I have ever seen and I have searched for them for five
decades. Perhaps very few were made and they would be of little
use to the everyday woodworker who would have no use for such a
This photo is a close up of the cutting head of the bit.
It is a good idea for such a tool
in that a single bit could be used, instead of two, for
installing a saw medallion.
