Whether you're cutting tatami mats or bamboo stalks, it's easy to bend the blade on a katana. Learn how to repair the damage with this essential advice from Carl E. Long.
If you regularly cut tatami mats or bamboo, you’ll become an expert at not only cutting but also bending or, rather, straightening your sword.

Even a well-manufactured mono-steel blade or traditionally folded-steel model will bend or twist if your technique is off.
