Later, at the end of the Warring States period, iron smelting technology appeared. At the beginning of the Han Dynasty, iron swords began to be popularized, and both junior officers and cavalry could carry swords (previously only senior generals had them). However, with the popularization, it also led to the change of war mode, that is, one-way slashing is more suitable for immediate combat and faster than stabbing. Therefore, the knife has replaced the sword as a conventional weapon of the army. The sword has returned to the decorative object of the status class. The sword we know now is only an ornament for the literati and the rich, and it has no advantage in war except personal self-defense.
Then, with the maturity and development of iron smelting, steelmaking, quenching, forging and other technologies, the saber was basically shaped in the Tang Dynasty, and now it is called tangdao. The prototype of Japanese Dao is tangdao. I have been practicing martial arts since I was a child, and the time is not short. But because I love fists and fists, I have always been dismissive of saber and fencing. It's pure deception. I can only say that after practicing for a few days, I will pose and fool people. It happens that my family has a Japanese knife seized in War of Resistance against Japanese Aggression, and China also has a knife and gun. So I have some perceptual knowledge in use, which can be compared intuitively in actual combat. Off-topic, because of this Japanese sword, I once studied Japanese kendo for a while, but more than 20 years ago, it was impossible for anyone to understand Japanese martial arts and teach it by hand, so I found some books and materials casually, but they were still fragmentary. In the end, I didn't even get a fur. The only gain is to know a few gestures that can make everyone laugh. ri:fo'4TO
Cut short the nonsense and return to one's muttons. NlKnMgt~
The design of Japanese Dao is very close to the hand, with excellent feel, reasonable radian and center of gravity. Dancing, chopping and stabbing are really top grades among soldiers. But in practice, I think it has at least two defects, which are enough to make it change from the handicraft status of the best cold weapon to the ordinary killing weapon like the China broadsword made by the railway track.

From the user's point of view, my personal opinion is that Japanese knives will probably be replaced by broadswords even if they are not replaced by firearms, and their craftsmanship will be preserved. After all, it is an excellent craft, but the shape is likely to change greatly. Even if it is preserved, it will become a ceremonial object, thus eventually withdrawing from the ranks of standard weapons. l^=>； )\R2$[
I think, if there were no firearms, there would probably be broadswords made by Japanese knife technology, which would eventually form a standard weapon similar to the old Soviet knife. The ultimate bully among soldiers would be China broadsword (I should be allowed to be happy here, although I don't want to shout patriotic slogans, and the derivation of this conclusion is not political or emotional, but there will still be a feeling of stealing happiness ...).

Unfortunately, this is just a hypothesis. After all, the era of firearms has arrived, and we can only guess and verify this problem in the end, but we can't verify it. :70oO}0m。
The blade of Japanese knife is narrow and slender, and it doesn't look heavy. But if you really use it, you will know that it is actually heavy. Don't try fake Japanese knives and craft knives sold in domestic handicraft shops, which are far from real Japanese knives in radian, weight and center of gravity distribution. The radian of the blade is very particular for knives, especially when chopping. When you hit a hard lump with a knife with random curvature, the nondescript curvature is enough to make the knife bounce back and hit a big blood bag and a big gap on your forehead, otherwise it will break and fly out. That kind of knife and a real Japanese knife are two different things. If you buy a local Japanese craft knife, that's another matter. D 1w_Vpz
I have been practicing martial arts for many years. Although my arm strength is not big, it is certainly not weak. Now you can do push-ups with two fingers, and your wrist strength and finger strength should be ok. y|@^0]}%<；
But when I wield a Japanese knife, I still feel quite hard. When Japanese knives chop, with the help of its radian and weight, they can really strike a thunderbolt, which is extremely lethal. However, if it is a single arm, the return of the knife needs to rely on the strength of the wrist and arm, especially when it is bottom-up or reverse. At this time, people like me feel a little awkward when using it, and it is not convenient to turn around. Even the two-handed knives can't be collected together, and it's a bit awkward to collect them. & ampu^| International Company
From this, I deeply feel that the handle length of Japanese knife is not only the function of adjusting the center of gravity, but also because it needs to hold the knife with both hands. Therefore, it is reasonable that Japanese swords are basically used with both hands from development to now. If you use one arm and miss the entrance and exit with one knife, it will become the "losing power" in the martial arts classic written by Qi Tiger, and because it takes twice as much effort to close the knife and turn around, there will be immediate life worries. Therefore, from this perspective, it is absolutely impossible for ordinary people to use Japanese knives with one arm. If nothing else, the requirements for wrist strength and arm strength will be considerable. Here, the difficulty of Musashi Miyamoto's second knife flow can be imagined. I think this person's wrist strength, arm strength and brawn will definitely surpass ordinary people. H P7Ec
Therefore, although Chinese and Japanese martial arts and knife methods have their own advantages and disadvantages, China broadsword and Japanese knife are also two-handed knives, but the blade thickness, width and length are different. Japanese Dao has a thicker back, while China broadsword has a wider blade and slightly different length, but they are all about one meter, which is almost the same. v7ae^iU
In this way, if two people are equal in martial arts, one can use China broadsword and the other can use Japanese knife for hand-to-hand combat, we can make a comparison based on these basic conditions. y，%w '
First of all, from the production, hardness, toughness and sharpness of knives, Japanese knives are undoubtedly good. tuv4 ~ i & lt
However, the blade of the broadsword is wide, so although the physical performance is poor, it can never be broken by a Japanese knife. In contrast, Japanese knives with higher hardness may have this concern. Just make up for this with the thickness of the blade, and everyone is even. However, the weight difference between the two sides is not very big, and the sharpness and hitting degree of the weapon blades of both sides are insignificant at the moment, because the blades of both sides are very long, and it is always impossible to hit all the blades of about sixty or seventy centimeters in battle. Besides, if you really kill them, life and death are just a few tricks. R ~cc]kp0
This brings us the problem of curling blades that many friends insist on. eZUK & lt& amp0x5
We can think about this problem carefully. First of all, we can be sure that the blade won't roll when cutting the first person (unless this person is lazy and hasn't sharpened the knife, then he is unreliable). After cutting a person, this blade can't be rolled until it can't cut into the flesh. We can only observe our own stainless steel kitchen knives, or buy a few pounds of pork chops or steak to try. Brother, I like to go to the kitchen. I have rich experience in using kitchen knives and don't need people to do experiments.
