Trying to slice a bullet with a Katana could potentially harm the blade.

Can a katana cut a head off

Absolutely yes, a Katana can cut a head off. Historical records highlight Samurai collecting heads as trophies to mark their victories in combat. Also in the famous suicide ritual Seppuku, after the samurai slice his belly with tanto, his kaishakunin will use a katana to cut his head off to end his pain.

Technically a good kaishakunin didn’t cut the head completely off, the best practice is to cut half the neck, and leave some skin to still connect the head to the body. All this should be done quickly to help end the pain and keep the respect, this is called “daki-kubi.”

Can a katana cut a person in half

Yes, a katana can cut a person in half, as matter of fact, this is called tameshigiri and it is how the ancient Japanese test the katana quality. They use bodies of executed criminals, bodies were positioned on a sand mound and secured with bamboo stakes. The tester, wear a kami shimo and armed with a blade set in a unique iron-bound hilt, would then analyze the corpse to determine the most suitable cut from his array of techniques.

The difficulty of the cuts varied. For instance, a cut at the wrist was deemed the simplest, while a cut across the hips, known as ryo kuruma, or a diagonal cut through the shoulder girdle, referred to as o kessa, were considered the most challenging. Following the cut, the body and the blade were meticulously inspected for any damage and signs of clinging fat. If the tester was satisfied, he might proceed with more complex cuts.

The outcomes of these tests were engraved in gold on the tang of the katana(nakago). Blades from different smiths were classified into five sharpness categories based on these test results. For example, a record exists of a short sword blade by Nagasone Okisato Nyudo Kotetsu, which had the test result of cutting through two bodies engraved in gold.

However, it’s important to remember that the sapling’s diameter should not exceed 3 inches and the alignment of the blade’s edge needs to be precise. If the edge alignment is off, the katana might become bent, especially for carbon steel blades. The composition within a tree, which is very different from human flesh and bone, tends to compress against the blade as it penetrates deeper, and any sideways motion could lead to the blade bending.
