You are killing me with the Iwasaki 50, @Mr Bedlington!
How wide is the blade and what is the grind? Hollow?
I only know about one Iwasaki western style razor that is near wedge/quarter hollow - the 30V. Do you know if he made any other near wedges/quarter hollows?
Hi, Frank, I purchased the razor quite a few years back from Japan, it was NOS with the original box it's a 7/8 full hollow,
On the box, is written 50, and Hv 812 (Hardened to Hv 812 on the Vickers scale = around 64 Rockwell) that's much harder than most straight razors.
