Hey Paul,
That sounds like an old plumber’s bossing mallet?  Giggle search for
“Lignum bossing mallet antique tool” or some variation of that and Bell
System Tools and see if your thingy corresponds.
Cheers from a snowy Waterloo, Ontario (where Spring might never come this
year.  Plus, the snow is so high this year that the rabbits were able to
girdle over half of my orchard trees above the protective mesh that covers
24” of trunk.  Years of work gone to  wascally wabbits.  All they left me
were their little fertilizer pellets… I have to laugh so I don’t go
ballistic, literally).
