Identification of Bayonette

[2015dmax]

I own this bayonette and scabbard with name and place of manufacture just would like information on what era it may have come from. Bayonette has Kiffe and Japan on it and the scabbard has Mangrovite 45 on it , any information would be appreciated . Thank you.
