I recently purchased a very old wakizashi in a bone shirasaya, but upon inspection I noticed the blade was forged with the last 1/3 of the top of the blade sharp (last 1/3 of the blade to the point). I was hoping someone could tell me what to call a blade that is sharpened on both sides like this so that I could do further research to determine the swordsmith or age of this sword. Any and all help is appreciated!


You could try contacting a swordsmith in Japan. Yoshihara Yoshikazu has a Facebook page that seems to be his official account, but I'm not sure: Swordsmith of Japanese sword ; Yoshikazu Yoshihara 【刀匠 吉原義一】 - Home | Facebook

If you message him, he might respond, but I think he speaks only Japanese, so find a Japanese-speaking (writing) friend to contact him, if you don't have that proficiency.

Alternatively, you could try to find an iaido dojo or sensei and show them a photo of the sword. I realize they generally use practice swords and/or longer swords like katana, but they may still be able to point you to a reputable swordsmith/manufacturer who could help you. At the very least, one of them might know the terminology for such a blade.

Otherwise there are a number of sword collector forums and individuals online who might be able to provide insight.

Usually bone shirasaya indicates a tourist piece from Meiji times.
A sword that is sharped on both sides is usually called a "ken", however a ken (剣) has a unique shape, and looks very different from a wakizashi. If it is a typical wakizashi shape with a sharp edge on both sides, the style is called "moroha zukuri. You can read more about this style here
