WWII Imperial Japanese Naval officer dirk of early 1883 pattern. These dirks were worn by all Navy commissioned officers.  This example is of later wartime construction with machine made blade, no Habaki or lock mechanism and a grip with double brass wire wrapped over imitation ray skin (the early dirks had real shark or ray skin).  The grip has the brass cherry blossom flower menuki mon symbolizing the emperor on both sides securing the mekugi (the small wooden peg that holds the grip to the blade hilt).  The saya (scabbard) is wood covered in leather with a decorative seam down the reverse.  The pommel is nicely ornate and the cross guard is wave shaped. This late WWII Imperial Japanese Naval officer dirk is in good condition and shows regular age wear.
