Hello Andreas,
I can feel with you. I have a blade with very tight homogeneous ko itame hada without any flaws and less hataraki. The hada is hard to see but maybe the polish is not the best. Then I have a blade with rougher more visible hada and a lot of nie and hataraki. I still does not know what blade has a higher quality but I prefer the second one. Does anybody know if a very tight homogeneous hada is indication of higher quality? It seems for tight hada you need more folded layers and this could be more difficult to achieve.
Regards
Manfred (still learning)
