I came upon a True Temper light hatchet with a long thin blade, and thought it
might be either a shingling hatchet or, more likely, a lathing hatchet.  It was
partially encrusted with plaster.  Cleaning it off, I found the words "GENUINE
UNDERHILL" stamped on the blade.

I also found an frustratingly inconclusive thread on "Lumberjocks:"

They don't seem it resolve the question of whether "Boston" on that example
refers to the pattern or the head office of the manufacturer.

The best part of that thread is the picture fin which the words "Reg. U.S. Pat.
Off." appear above the word "GENUINE".  I know little about "Design Patents,"
which I presume this to mean.

First Question: Can one search Design Patents online?

Second question: When did True Temper absorb Underhill Edge Tool?

Unlike my other lathing hatchet, this one has a longish blade which might be
useful for chopping a rough mortise in a timber. My inclination was to sharpen
only one side, like a chisel.  A couple of cursory whacks on a Oak fire log
shows it lacks enough mass to do much in hardwood!
