The kerfing plane and frame saw are a set of complimentary tools from a bygone era of woodworking where everything was done by hand.
These are some specialty tool bodies made for Bad Axe Toolworks in Superior, WI. They are a repeating job that I’ve enjoyed developing and refining the build process.
Bad Axe is a great small business selling the absolute highest quality hand saws. Check out their badaxetoolworks.com
