One of the most distinctive features of the katana is its curve. But why are katana curved?
Katana curve
The katana curve is called "sori". There are a few reasons to explain why katanas are curved.
1. First, the curve allows for more efficient cutting. When you swing a katana, the curve helps to guide the blade through the target, resulting in a cleaner cut.
2. Second, the curve makes the katana stronger. A straight blade is more likely to snap under pressure than a curved one. The curve also helps to distribute the force of a blow more evenly along the length of the blade, preventing it from shattering.
3. Finally, the curve makes the katana lighter and more balanced. This is important because a katana is designed to be used with one hand, and you need to be able to handle it quickly and deftly. A heavier, more unwieldy weapon would be much more difficult to use in this way.
So there you have it! The next time you see a katana, you'll know why its distinctive shape is not just for show, it's an essential part of its design.
