Just recieved a sword by the same maker yesterday. Kinoshita Yoshitada , no 1 seat RJT swordsmith in the same mounts as yours and same date. Through microscopic examination my sword exibits hand made water tempered qualities such as hada, nei and abundant large martensite crystals. I am as far removed from an expert as you can get but have worked out a system that works for me totally non scientific. I own a control group of swords (15+) that i use for comparison eg non trad mill steel etc, trad made tamehange water quenched, oil quenched etc. My sword exibits the qualities of a handmade waterquenched sword?
Also i have seen two examples of swords in 44 mounts in the last two days by this maker that are for sale for around $4000 Aud or Us
To give an example i have a sword made by "nobumitsu" who is classed in Sloughs as low grade showato, the one i have is clearly handmade waterquenched so there is always an exception to the rule.
Thanks
