I asked Brian last night..The reason that swords are curved is simply because of the processing. The fact that the blade is hammered on one side, causes the metal to curve.I am sure that he will elaborate :mrgreen:

Yes, please! I'm actually pretty interested in learning the clear answer.

The martensite crystal is dimensionally bigger than those of pearlite, hence the blade takes on an induced curvature.

That's because Hollywood has Ninjas using ninja-to's, which are shorter than katana but longer than wakazashi.

They are straight bladed multi-purpose tools/swords.

I once heard that people started creating curved blades because it was easier and faster to draw from a sheath than a straight edged blade

Did you even read the rest of the thread?

I heard curved *****es were faster to draw from an ass than straight *****es.

I heard the same thing on another show on discovery. It was probably Daily Planet.

Yeah, for some reason it was a big deal to be able to pull the sword out in a swinging motion

Why swords are curved

Has to do with the forging process..

a bar of iron\steel if forged to a edge on one side will induce a curve in the bar as one side gets squished flat it lengthens that edge.

In the heat treating process this curve can increase slightly.. but the curve of a one edged sword is established long before the heat treating.

People have proposed all kinds of **theories** as to why swords are curved, many of these theories are even presented by so called "experts".

the curve has nothing to do with being easier to draw, better cutting, deeper cutting... all of these are simply not true. They belong to the world of "fantasy" and mystery surrounding swords. Which unfortunatly many of the "experts" have served to perpetuate rather than destroy.

Deeply curved swords do present some advandages in fencing with them.. as they can be very deceiving in the transition between a cut and a thrust and can force an opponent to overcommit to a defense. This is well illustrated in both the Polish and Italian dueling saber traditions. But Japanese swords are not curved enough to take full advantage of this property.

And finally to abolish the myth that the Katana is the "best cutting weapon devised by man" The techniques of forging the Katana and its shape and properties is a direct result of the very poor quality of iron ores to be found on the island of Japan. The Katana is without a doubt a very effective cutting sword.. and it is the best cutting weapon that could be devised on Japan from the materials extant. **However**
Katanas as a class of sword are heavy, unweildy and poorly balanced and prone to bending (and staying bent) in comparison to European swords forged hundereds of years earlier. In Europe there was no shortage of very high quality iron ore, and in fact European smiths had abandoned in the 11th century the process to make blades still in use in Japan in the 17th century.
In Japan.. because the quality of raw materials did not improve over time.. neither did the methods to manufacture weapons from them. This coupled with the cultural predisposition to venerate tradition kept the Japanize Katana frozen in time in both form and function.

Europe by contrast developed advanced metalurgy and steel making centers early in the middle ages. by the 10th century many swords were forged of high quality carbon steel.. a material that simply did not exist on Japan in any significant quantity. and this trend expanded as time progressed.. by the 14th century steel manufacture in Europe was highly advanced and consequently the edged weapons created by sword smiths standing on a thousand years of sword making tradition reached a peak of design and function unparalleled anywhere else on the planet. Directly after the 14th century the "age ofthe sword" deminished replaced by the "age of the Gun" that is even today still dominating our culture.

some blades were being made curved for very practical purposes like cavalry swords; cavalry swords were given a cruve so that they wont cut the heads of the horses as the sword was swinging; there is also a potential aerodynamics discussion...
i wasnt aware of the stuff brian wrote up until now, pretty cool to find this stuff out.
