This style of bayonet is commonly known as the "Last-ditch".
The following is a rare and fine example of a WWII era Japanese wooden scabbard bayonet.
Wooden scabbrds did not come about until late war. As the fighting approached home and the
naval choke hold of the islands was started, the military was running out of raw materials and
was forced to improvise by building equipment from whatever was available. The condition of
the blade of this item indicates that it was possible never was issued.
The scabbard is a two piece construction tied together by tightly wound string. Another
interesting aspect of its construction is the square metal tip. The author has seen a bayonet
of similar construction with the exception of having a pointed tip that closely ressembled the
shape of the blade tip.
The picture on the left (below) shows the serial numbering found on the tip of the handle.
While the picture on the right depicts the arsenal marking found at the base of the blade of the
bayonet.
