I would like to know if anyone would know what type metal is used to make
coulters from farm machinery.  They are used in plows, planters and other
farm machines.  The ones I have are 1/4" X 14" circular disks but not dished
like a disk blade.  Also what type material would a disk blade be made of.
The coulter cuts easily with a file and I have not tryed hardening it or a
spark test.  Thanks
