I've tried to look a bit further into W.B. Gregory's life.  W.B.
(William B.) has this written about him in "A History of the Northern
Peninsula and Its People"  from Google Books:

"William B. Gregory, grandfather of him whose name introduces this
sketch, was a native of Yorkshire, England, as was also his wife, and
in England were also born their four children,=97three sons and one
daughter. The family moved to America in an early day, and the
grandparents passed the closing years of their lives in the Lower
Peninsula of Michigan. William B. Gregory, the grandfather, was a saw-
maker by trade and followed his trade for a number of years in Albany,
New York, whence he finally removed to Muskegon, Michigan, where he
engaged in the manufacturing of saws and other mechanical appliances
and where he continued to reside until his death, having been one of
the pioneer business men of that city."

Seems that perhaps W.B.'s saws looked the way they did was a result of
his (possibly) earlier work as a sawmaker in England and he may have
brought the same design to his business in Albany.  Just speculation.
