I recently came into possession of a collection of blades from different eras, And different countries. Among these are a Shin Gunto, and a Japanese Dagger that appears to be of military issue ( I will create a separate post )
I don't know much about these, so hopefully I can get a little bit of help.
I do not know how to disassemble the blade, so these are the pictures I could get. The blade edge seems to be a little rough, with some notching in places, a d scratches...
Numbers match on both the blade and the sheath..
