I had a set of these once upon a time and played my best golf with them .
Gave them to my nephew years ago when he started golfing. I can't think of anything similar off the top of my head in today's irons. They had a mid / large size head, a fairly narrow rounded sole and a topline that was narrower than a something like a Ci11 but not at thin as a blade. The cavity was also pretty shallow.
