Were WW2 katanas more for chopping up civilians & pows than for fighting?
The vast majority of katanas carried by Imperial Japanese officers in WW2 were mass-produced pieces and of much lower quality than a truly good one. Also, contrary to popular belief in the West, the majority of the soldiers and officers were NOT descended from the samurai class and carrying out the traditions of their 'samurai' forefathers.
In Taiwan, I had a Chinese martial arts teacher who was very pro-Chinese, but told me that the Chinese Miao Dao was designed as a result of Chinese forces armed with Chinese broadswords losing skirmishes with Japanese pirates, who were often ronin (masterless samurai) and who raided China's coastal areas centuries ago. They found that the Japanese method, much simpler and direct, using a 2-handed grip, and their aggressive and fearless attacks, gave the Japanese pirates a big advantage, even against greater numbers. He told me that the Chinese created their own sword based on the katana to deal with that problem. He said that the assertion many Chinese made that the Japanese copied the Miao Dao to create the katana was B.S. I don't know if his information was right or not (I haven't googled it or anything), but that's what he told me.
I'm descended from samurai on my mother's side, and once an older cousin brought out a valuable sword that had been in the family for generations, and was powdering the blade. Unfortunately, I was a kid and wasn't overly interested, but I was impressed with how perfect it looked. Of course, his rule was, 'you can look, but don't touch'.
