Blade 刀身 Tōshin
Blade Notes
Blade Note 1: The early blades had the notches for the habaki aligned. This is the traditional style used on Japanese swords. The lowest observed blade is serial number 857 and the highest is 6320. In addition, there was only one hole for a grommet screw toward the rear of the tang.
Blade Note 2: About the time when the handle was changed to aluminium, offset notches for the habaki were introduced. The lowest observed blade is serial number 7249. The lower blade notch engages with a built-up dam inside the lower part of the habaki. Also, a hole was added behind the habaki for a brass or steel mekugi.
Blade Note 3: The nakago [tang] can be found either marked or unmarked. Occasionally arsenal symbols or company logos are seen. Serial number 6320 has a Kokura Arsenal symbol, while serial 209247 has a Seki Tōken KK logo. The most common marking encountered are army inspection marks. The following army inspection marks have been noted on the tang: 東, キ, ホ, 名, 関, M.
Blade Note 4: Some of the early Type 95s were used by officers and have kanji numbers chiseled into the lower tang.
Blade Serial #
The Kokura serial number is read with the blade edge down while Nagoya & Jinsen Arsenal is read blade edge up. Some Jinsens have the first digit overstamped with a 3. The overstamp can be faint or partial, making the first digit hard to read.
Blade Inspection Marks
The early Suya made swords did not have a visible blade inspection mark by the serial number. Instead, it was stamped on the tang and thus covered by the hilt. This occurs early on in two distinct blocks of serial numbers.
Kokura & Nagoya used a final inspection mark, either before or after the serial number. On Kokura, it comes after the serial number, while on Nagoya it comes before. In the Nagoya two hundred thousand range, the final inspection mark is occasionally stamped behind the serial number. Jinsen used the Heijō Factory inspection mark. In addition, Jinsen sometimes used an extraordinary inspection mark that will appear either before or after the Heijō Factory inspection mark.
The individual inspection marks can be seen in the “Inspection Marks” section above.
Blade Fullers
Blade will be either fullered or unfullered. The original design was for fullered blades; but, late in the war some arsenals and civilian companies omitted the fuller.
