This is a set of prototype irons that were never released publicly.  It is based on the same mold as the very first SEVEN CB. ( non-milled version ) The reason for this prototype was to see and measure the difference a larger bump behind the hitting zone would create.  The result was positive but shortly after SEVEN began moving toward Full CNC.  This is a very rare iron.  The material is S15C and the PW is based on 46*. It was manufactured about 2012 - 2014 100% in Himeji Japan.  The grooves are pressed as is the logo while the back cavity is milled.  The heads are hand-ground Oichi forgings.
