Yea so last march i was at kyoei and started looking at their past molds.  pain of a job as these things are heavy to move.  They have stuff that wasn't touched for decades but they are sitting on a gold mine.  

came up with this design and concept using the K1,  their first blade mold.  Lot's of history on this mold. Many victories a long while back.

Very little offset,  very classic lofts,  strongest I could make the PW was 48*.  will post more pics when the weather improves.
