Toledo steel is basically two different types of steel (one high and one low in carbon content) that are forged together. The steel used in both places could have come from a wide range of sources, but would of been of variable quality. Meanwhile, when the katana was put under the continuous stress of a stream of .50BMG machinegun bullets, where the hard metals supported by the more ductile soft metals couldn't absorb/vibrate enough to cope under impact (you can see on the slow-motion review how the blade remained still and instead chipped/broke), that there is a limit to the kawa-gane's hardness despite its extreme sharpness and high quality toughness. Japanese steel was not particularly advanced, so unfortunately it would be very much outperformed by modern steel. The name "crucible steel" might throw you off as many can use it to describe specific blades. The Germans made nice swords as well.I prefer a Toledo blade ,in a high quality sword Stainless steel is excellent for making knives, however when it comes to longer blades, it tends to be very brittle, and usually swords made of stainless steel are for decorative purposes only.

How to find out if this sword is real or just a souvenir? [citation needed] Production. On math papers and general questions they need to address. Another big factor is the consistency of the steel.

Japanese sword comparison: youtube /watch?v=I5zecWQQ2zU. Do note though that the kawa-gane withstood at least four to six shots before the core/center of the blade with the softer steel was hit by the seventh shot which caused the sword to instantly snap while vibrating side-to-side because of the impact. Kings from all over the world had special weapons crafted in Toledo using the Toledo steel. However, when a modern steelmaker takes care and only uses pure materials and careful processes the result will be far better than ancient steel. This could be repeated several times, less than 10 I would presume. While some evidence may suggest Damascus steel dates back to 300 B.C., the first mentions of the famed steel date back to between 300 and 500 A.D.

The Toledo sword became known for its strength and durability, and soon became the most sought after weapon for Europeans. "lamination" in the samurai sword is NOT "pattern welding", You tube with a swordmith "laminating" steel, this is one of the smiplest lamination styles, there are far more complex, lamination begins at 1;40, here are links for adding carbon in the samurai sword, and other products as ingredients during the forging process 2. A well-made historical Japanese sword can easily cut any comparable European or Arab sword in half, but this is because of the temper and forging, not because of the quality of the steel. Why does the bullet have greater KE than the rifle? Aesthetics- Many chefs like the visual appeal of Damascus steel as it has distinctive patterning. So, to answer the original question of a comparison between the three kinds of steel, I doubt that you would be able to find anything that addressed it without doing so in the context of making blades, as steel that was used for other purposes was typically of a different formulation. For most projects and uses, though, it’s plenty strong and durable. Against whom was the Tree of Life guarded after the fall of Adam and Eve? Ancient steel, pure and carefully made, can exceed such steel in quality. An interesting professional article on the theme, much more thorough than my answer: http://www.tf.uni-kiel.de/matwis/amat/def_en/articles/vikingsword/blade_patterns_intrinsic.html. Having any phosphorus, sulfur or mercury is always very bad. A couple of the claims written in the answers above need to be discussed with counter points; The ancient Japanese samurai sword that we are talking about was specifically developed to address the brittle nature of steel that time, no it was not brittle by yesterday's standard or today's. Good answer but could be improved with some references, or examples of contemporary formulas. Good damascus will take and keep an edge as good or better than their individual steels. Toledo steel consists of two steels of different carbon contents welded together by hot forging. Does the starting note for a song have to be the starting note of its scale? interesting you would claim deep misunderstanding of metallurgy, a lack of sources, then make counter claims without sources. Now some people might be under the illusion that katana or the tamahagane is really great (or popularized in both fantasy and reality) because of its mere hard properties.

The quality of a sword is determined by complex aspects of forging and tempering, not so much as the quality of the steel. The edge was case hardened further in a process known as "clay tempering", different types of clay insulating the blade to different degrees to produce different levels of hardness in the final forging process. Most functional samurai swords are made out of high carbon steel. Damascus Steel vs Stainless Steel Chef's Knives: A Question of Taste? Many people often have questions about Damascus Steel, or folded steel, thinking that it is the best steel for swords - but in reality, what we currently call 'Damascus Steel' is just any of the steel types above that has been folded several times..

As far as I know, the Japanese folded steel is exaggerated. Folding does more then remove impurities, the folds seem to add a level of strength and pliability, or "toughness", a grain is produced that could also be manipulated to add differentiating strengths to different areas in the blade, like alternating the grain of hardwood. Therefore, if you have a pattern welded Damascus steel knife with acid etching, it is a legitimate and real Damascus steel knife. Almost every historic novel I read in my childhood featured a rapier or a sword “made from the finest Toledo steel”. This, however, is dependent on each specific sword (saying all swords made and used by soldiers within the time period of one year were all made with one specific process would be extreme). Soon, it became a standard source of weaponry for Roman legions. Damascus is a style of metal that is folded but beautiful. After that folding and sandwiching process, the folding then is not the same as done today, there were layers of other products added between folds with indigenous ingredians, this "recipe" is probably lost, though some smiths in japan claim to still have it carried down. ... 45002 Toledo (España) +34 925 223 586. info@artesaniamorales.com.
