In this article, we explain why it is sometimes even bad when a sword is made of folded steel!\n<\/p>\n

Why is the blade steel for samurai swords folded?<\/h2>\n

\nFolding serves to improve the properties of the traditional<\/u>\u00a0Tamahagane steel. Folding removes impurities and the distribution of the components within the steel becomes more even with each subsequent step, until the distribution is almost completely uniform (homogeneity).
\nWith traditional steel grades, folded blades therefore have significantly better properties than blades that are not folded. With industrial mono-steel, folding tends to worsen the quality, as explained below.\n<\/p>\n

How many times has the best katana been folded?<\/h2>\n

\nThe steel for the blade of a katana is usually folded about 10 to 15 times. The steel actually only needs to be folded as many times until the inner components are evenly distributed. With each folding step, the steel releases carbon content. Once it is evenly distributed, it is only folded to achieve a certain carbon content. How often the steel is folded for a blade depends primarily on the quality of the raw material used. Therefore, the rule that more folds or layers make a better sword does not apply!\n<\/p>\n

How many layers does a sword made of folded steel have?<\/h2>\n

\nThe number results from the number of times the steel has been folded. To calculate the number of layers, the number 2 is multiplied by the number of folds.<\/p>\n

Examples:
\n5x folded: 25<\/sup>= 32 layers
\n10x folded: 210<\/sup>= 1024 layers
\n15x folded: 215<\/sup>= 32768 layers
\n20x folded: 220<\/sup>= 1048576 layers<\/p>\n

As explained above, the number of layers does not indicate the quality of the blade!\n<\/p>\n

Does my sword have to be made of folded steel?<\/h2>\n

That's kind of the core question of the whole thing, and it depends above all on the steel used for production.<\/p>\n

Traditionally produced Tamahagane steel should always be folded in order to achieve the improvements mentioned above. Standardised mono-industrial steel does not necessarily have to be folded, as folding does not result in any improvement. Similar to the Blade construction\u00a0<\/a>With this steel, less is more.\n<\/p>\n

Folds on medium-priced swords<\/h2>\n

\nMedium-priced swords (everything up to approx. 2000 euros) are usually made of industrial mono-standard steel. A short list of examples of industrially manufactured steel grades can be found in this Article about steel grades<\/a>.
\nSome sellers of these swords suggest that a blade made of folded steel is of higher quality than blades made of non-folded steel. But the exact opposite is the case!
\nIndustrial monosteel has no impurities and is already largely homogeneous. Folding is therefore generally not necessary. Folding only reduces the carbon content of the steel and therefore the hardness.<\/p>\n

If industrial steel is poorly folded, this can also reduce the quality of the blade (e.g. due to air pockets etc.)! In the case of standardised mono-steel, the rule of thumb is that a cleanly crafted, unfolded blade has better properties than a blade that is folded. Even if this steel is perfectly folded.
\nBefore you buy a very cheap folded sabre made of industrial mono steel, we would recommend a sabre made of non-folded steel in this case in terms of quality!
\nFolded steel still has many fans, however, because folding can result in an attractive pattern. Of course, everyone has to judge for themselves how much this is worth.<\/p>\n

So don't let false information take money out of your pocket unnecessarily.
