Fellow enthusiasts:
In an effort to find out as much as possible about my wakizashi, I started to research the reasons for two mekugi-ana, one of which was drilled/punched through the mei. After reading multiple threads on NMB, I came across an article by Tanner and Coutinho that I thought presented an interesting theory on the topic. I was hoping to get your collective input as to the validity of the theory they present.
In reference to the placement and number of mekugi-ana, Tanner and Coutinho (2019) contend there were factors related to fashion and style, rather than suriage or tsuka length, that precipitated adding another mekugi-ana. They note that:
“In the kanagu of the latter part of the Muromachi and Momoyama periods, short fuchi with low koshi are conspicuous and thin tsuba are more prevalent. On the other hand, in the beginning of the Edo era, the koshi of the fuchi became long and the thickness of the tsuba increased. Therefore, the position of the mekugi ana was moved away from the imaginary line connecting the ha-machi to the mune-machi.”
At least some of their conclusions were drawn because of the consistency in distance between the original mekugi-ana and the later addition in the swords they sampled. Specifically, they found the two mekugi-ana were 1cm apart on tanto and 2cm apart on wakizashi and katana. Additionally, Tanner and Coutinho (2019) suggest the ana added at a later date is most often the one incidentally put through the mei. I suspect most of you have read this article before, however I have included the address below for those who haven’t and would like to.

Thank you for your input.
