The dark red velvet lined mahogany case with
inlayed brass handle measures 6.25 x 9.5 x 1 3/4 inches.
The trephine cutting heads
are cylindrical with vertical 'escapes' for the bone debris, similar to those
vertical slots seen in some capital saws from the 1850's.
Note the
Hey saw is blued, which is unusual. Also, note the rather basic, yet
functional design, and fit of the handle.
