Snip
From: Steve Jones






No, no, no. The problem with making a hexagonal pencil round by subtraction
(planing, turning, dowel machine, dowel plate) is that you make it smaller
in diameter. That would negate both the comfort factor and the fit in the
divider. You could make long, skinny scales to glue onto the flats (with
hide glue, of course), but that seems excessive.

Excessive? Perhaps. Genius in concept though. 
I propose coopering a pencil holder that will accept the less appealing shape
and envelop it in a wooden sheath of the appropriate diameter and heft. Perhaps
jarra or cocobolo in the absence of ebony, the hands down favorite.
Or just buy the 8 pencils at $50.00 each and sit in a darkened room muttering,
“My Precious, My Precious”
Written by a guy who has spent many an hour cleaning the saw plate, refinishing
the handle, sharpening the teeth, and (take a deep breath) polishing the brass
on a D8. It just looks stunning in the saw rack, and feels way too good in use.
