Swords can break, if the forces are right. It’s not supposed to happen but it did sometimes. Japanese swords vary. Most are a bit harder than the average European sword, and while hardness helps with sharpness it also makes a blade more brittle.

The longsword is a longer, heavier sword with more stopping power, while the katana is a shorter, lighter sword with a stronger cutting edge.

The khopesh also came to have ceremonial value and was often depicted in art or included in the tombs of prominent Egyptians. The khopesh was eventually abandoned in favor of more traditional swords around the 12th century B.C., but not before it had become one of the most iconic weapons of ancient Egypt.

Considered by some to the finest cutting weapon ever designed, the Katana wins hands-down here. Made of harder steel, the Katana flexes less than a Longsword and can hold a sharper edge, allowing more force to be applied consistently across a smaller surface area.

Another reason the traditional Japanese katana is regarded as being the world’s best sword is that they were forged using differential heat treatment. This involves heating and cooling the katana’s spine and edge at different rates, thereby creating a stronger edge and a more flexible spine.

As nouns the difference between khopesh and scimitar is that khopesh is an egyptian sickle sword while scimitar is a sword of persian origin that features a curved blade.

The high carbon steel (tamahagane), and the remelted pig iron (cast iron or nabe-gane), are combined to form the outer skin of the blade (kawagane).

Katana’s are sharper/harder than western swords, but that means they chip or snap easier than western swords.

In the past, Katana was used by the Samurai in combat sport, duels, and ancient Japan’s bloody battlefields. In the modern age, war has changed, but even today, depictions of Samurai in popular culture show that the Katana was the weapon of choice of these elite warriors.

The Khopesh is an exotic weapon. It was similar to an intermediate between a sword and an axe. The blade and its hilt are both completely made of metal. The blade sweeps out into a cutting edge with a curved design. Some consider this as an ancestor of the Falchion which is a heavy sword for chopping.

A Super-Trope to Wooden Katanas Are Even Better, in which the ultimate sign of a Master Swordsman in Japan is being able to defeat steel katana using a wooden one. If a fan fiction protagonist’s Weapon of Choice is a katana, and especially if they wield two at once, it can be a giveaway that they’re a Mary Sue.

Plenty of other master-level swordfighters in the series use only western-style blades too, such as Vista, Cavendish, Rayleigh, Cracker, Whitebeard, and Kyros such that the series either depicts Japanese blades and western blades as equals or the katana is a rare and specialized weapon.

For the blade and hilt of the Khopesh, these are cast in a single piece, making the weapon more durable. Its length is usually 500-650. Most of the surviving samples are heavyweight and have a cross-section that is fairly thick. However, it is not certain that all of the weapons were used for combat since some ladies are unsharpened.
