gets confusing, a well known tale about an incompetent UK executioner who took a few blows with his axe to remove a ladies noggin, he used what was in actuality a carpenters side axe, used to square beams that had an offset blade with a chisel edge and wasn't designed to chop necks. It's designed to shave a vertical surface of a log flat, not chop stuff.
By the way, searching for a carpenter's side axe i found this modern one. Looks familiar.
I seem to recall us discussing army wagon drivers carrying axes for their use which occasionally got pressed into service if they were attacked, turned out they were also carpenters side axes. apparently many are sold as 'battle axes'.
I also note the originally posted one does NOT have the offset of a carpenter's side axe.
