Just received another Disston Reagan Patent back saw, 12" 12pt rip. The plate measures .088 thick at the tooth line and .045 at the spine, almost 4X thicker than any other saw i own. It's mostly sharp and cuts straight and true. The tooth line is breasted approximately 0.10.
Could this be meant for something other than wood? Metal? The #9 above it has a .023 thick plate
