The Japanese Police utilized four (4) distinct styles of short swords for lower ranks according to Jim Dawson in his book, "Swords of Imperial Japan 1868-1945". Dawson shows these four styles of short swords in Chapter 24 of his book and calls them Police Bureau Swords for Patrolmen (junsa) and Sergeants (junsa-bucho). Bear in mind that these Japanese Police swords are very diverse and not yet fully understood by collectors.
I will use Dawson's nomenclature and show two Style 3 Police Swords/Daggers. The first short sword is similar in style to other Patrolman and Sergeant rank swords. The brass hilt does not contain a Police badge and does not have a full D shaped guard as does the Style 4 short sword. The Style 3 and Style 4 swords are differentiated by the full D shaped guard on 4 and partial guard without a knuckle bow on 3. Some Style 3 swords will have markings indicating they are the property of a city police department along with a serial number. The brass hilts often show signs of gold plating and can have sharkskin or leather grips. The short blades are typically machine made or reworked from older blades. The steel scabbards are nickel or chrome plated. The sword knot is the standard brown leather knot seen on other NCO swords.
This short sword has a marking on the underside of the guard indicating it was made by Toyoda. Also notice that the scabbard has a removed second ring mount indicating this early style was brought up to date by removing the secondary suspension ring.
