We can tell a fair bit about use of a lath axe from its tracks left behind. The different cuts: straight perpendicular to cut length, rarely through cuts mostly scoring then snap, angled perpendicular to he face, a kind of scarf cut, perpendicular to the edge along the roof line mostly done in two cuts ( I don't know how they would avoid blowing out he bottom edge but they did. Finally splitting/trimming in the length to fill a gap.
