- n. A cross-cut saw used to prepare logs for the saw-mill by cutting off the rough ends.
Sorry, no etymologies found.
Big timbers go directly from the saw on the rolls to the back end of the mill, where the first end is trimmed by a butting-saw or cut-off-saw which swings, Fig. 48.
The timber is then shoved along on dead rolls and the last end trimmed by the butting-saw to a definite length as specified, and shoved out.
