What is a katana?
Katana is a type of traditional single-edged Japanese sword, around 70-90 cm long, and with a curved blade. Katanas were very popular during the age of samurai (from 12th to 19th century), although they weren't used as much in open warfare as they were in duels, demonstrations, and other civilian purposes. They were often carried in pair with a smaller wakizashi.
Multiple kinds of steel are used in different parts of the katana blade. The traditional forging methods (repeated heating, folding and hammering) and the high quality Japanese steel with a lot of carbon content are the reason why katanas are one of the sharpest, strongest and most flexible edged weapons in the world.
Real katanas are still made in Japan, by using traditional techniques and materials. They can be very expensive and even difficult to buy. There are a number of low quality reproductions available as well, but these are machine-made and only good for show. A low quality reproduction can cost anywhere from $20 to $200. A high quality reproduction, which are heat-treated and can actually be used to cut something, can cost up to $1000 or even more.

Sword vs Bullet!
While good katanas can cut 9 mm bullets fired from a pistol with barely any visible damage (see the other videos below), they are no match for a military M2 heavy machine gun.

Well, not really. Katanas are beautiful and elegant weapons, but they are not magical.
How a katana is made
The process of making a traditional Japanese "samurai sword".
Nowadays only a few Japanese smiths who have a special license can make the real katanas which they call "shinsakuto". The forging of a Japanese blade typically takes hours or even days and sometimes involves several people. The steel is repeatedly folded, heated and hammered which eliminates the bubbles in the metal and spreads the elements evenly throughout all of the blade, thus increasing it's strength.A typical Japanese katana has only one edge, which allows them to use the rear of the sword to reinforce the blade. A katana is usually made from several layers of metal which are forge-welded together. The traditional "makuri-gitae" design, for example, has a softer inner core, and hardened metal on the edges.
After the blade is created, it is given to a polisher who uses up to seven different stones to give it a perfect look. The polishing often takes longer than the actual forging, and greatly improves the beauty of the blade.
From there, the blade is then given to a hilt-maker, who creates the grip, the hand guard, and other elements. The sheaths and the hilts are often decorated and ornate.

Oh wow! what a great lens! I've always wanted a Katana, plan to get one later this year. I tried to feature this lens, but found out that the feature module doesn't work with Ever sites, so I'm adding it to my link list instead. Here is the URL if you want to see where I put the link: http://www.squidoo.com/LordSesshomaruCostume Posted March 11, 2008 |

Hehe, that's true. Plus, you'd need to be so lucky as to hit the bullet in the first place. Posted March 09, 2008 |

They are sharp....but....what is the point in cutting a bullet in half? Instead of getting killed by a whole bullet u will get killed by 2 halfs of a bullet. Posted March 09, 2008 |
This would be an excellent backup for my MP5 as I walk my rounds as a Rapid Response Officer at the Mall of America.

if you are looking for really high quality reproductions. Search for Paul Chen, he is a fantastic sword smith.

Hi, I'm Chadrew
There's something beautiful in the fluid movements of a warrior wielding a katana, don't you think?
