Ok so just 4 reassurance the stamped side is hardened like high carbon and the non stamped is iron. So how does the life of the razor hold up? (how Maney years) and how thick is the hardened side? (1/16") also the stropping. Since the shape of the blade is so much different than wedge shaped or hollow ground. if the life of the razor is shorter term than our normal grinds which kamisori is the most cost efficient, and which is the cheapest acceptable quality kamisori? And the only other question I have is honing what grit home would you need to finishing polish the edge? Is 12k ok or do u need a 30k? How would you get this type of razor "sharper" than our everyday full hollow ground? Thanks ahead of time by the way.
