The term "Gunto" refers to a type of Japanese military sword used by the Imperial Japanese Army and Navy during the early 20th century, particularly during World War II. The length of a Gunto sword can vary, but generally, they were around 90 centimeters to 100 centimeters (35 inches to 39 inches) long.

Guntos were typically longer and heavier than traditional Samurai swords, such as Katana or Wakizashi. They were designed to be more robust and practical for military use. The overall length of a Gunto sword, including the blade and the hilt, would typically fall within the range mentioned above.

It's important to note that Gunto swords were standardized for military use, and variations in length and design could exist based on the specific model and purpose.
