A tanto is a traditional Japanese dagger or short sword. It typically has a blade length between 15 and 30 centimeters (6 to 12 inches), although there can be variations. The tanto is characterized by its straight blade and often has a single or double-edged design.

The tanto has a long history in Japan and served various purposes throughout different periods. Originally, it was used as a weapon by samurai warriors during the feudal era of Japan. Its compact size and sharp blade made it suitable for close-quarters combat and as a backup weapon.

The tanto's design evolved over time. Early tantos were primarily stabbing weapons, while later versions incorporated cutting edges. Some tantos have ornate and artistic fittings, reflecting their value as status symbols or ceremonial items.

In addition to its combat function, the tanto had utility uses. It could be employed for daily tasks such as cutting, slicing, and carving. The tanto's sturdy construction and sharp blade made it a versatile tool beyond its role as a weapon.

Today, tanto swords continue to be appreciated for their historical significance, craftsmanship, and aesthetic appeal. They are collected by enthusiasts, practitioners of martial arts, and those with an interest in Japanese culture and weaponry.
