An inherited Wakizashi

[Lookin4answers]

This is a third sword I have in my possession that I would appreciate any input regarding its possible origin and age.

 

I’m sort of stumped here in trying to describe or attribute names to the features in the Hamon and Boshi.

 

The Hamon presents in three separate sections. The lower 8 cm. of Hamon is Suguha and to me seems to be of medium width. The border of the Hamon in this area is delineated with a narrow line of Nioi. This transitions into a middle portion exhibiting a Midare form, but I’m not sure what the correct names are for the Hataraki that seem to be present. In this portion, the Nioi-guchi seems to rise above the brighter part of the Hamon incorporating darker parts of the Ji and then dives into the Hamon resulting in wide bright patches of Nioi along the Hamon. The last 8-9cm of the Hamon again returns to Suguha, but it is seemingly wider and even perhaps more diffuse than it is in the lower portion and very hard to see a Nioi-guchi line. I have tried my best to capture some of these features in my pictures. 

 

Forgive my inexperience, but for the life of me, I can’t seem to put a name to the pattern of the Boshi. It really does seem to be a random pattern of tempering, but I just don’t have enough experience to really make a determination. Hard to capture this well in pictures.

 

• The sword is a Shinogi-zukuri Wakizashi, based upon a total length of 67.8 cm. The Nagasa length is 54.8cm.
• The Kasane (Motokasane measured at Mune) is 6mm in thickness and the Kasane (Motokasane measured at the Shinogi) is 4mm.
• The Mihaba measures 3cm. The Sakihaba measures 1.9cm, seemingly a moderate amount of taper for this length of sword.
• There is 1 Mekugiana.
• The Hada appears to be Itame mixed with some Mokume in the Ji and Masame in the Shinogi-ji.
• Sori=1.3 cm. Toriizori form.
• Appears to me to be Chu-kissaki.
• Iori Hikushi Mune.
• The Nakago length is 14.4cm and is Kengyo-jiri. The Yasurime is Kattesagari. The file marks are very light.
• The sword is Mumei.
• The polish in general is fairly bright.

I would be interested in opinions as to when this sword was made, and in what region or school. Any other details or explanations regarding the defining features would be appreciated as well. Please forgive my ignorance. I'm reading and learning as much as I can, but the volume of information is overwhelming and putting 2+2

together is challenging.

 

Again, thanks to all who reply for any insight you can provide on this sword. I appreciate the enormous body of knowledge this site possesses and the willingness to help educate.
