  1. Katana is curved, but that curve is not such that it gives the blade much easier cutting properties. Of course, it helped, but that is negligible. For the curve to be such to play a vital role in the cutting the katana should be curved much, much more. The curve on the katana comes from the cooling techniques, when the swordsmith plunges the hot sword in the water the metal gets curved. And again, I am not saying that the curve is not helping, but the curve on the katana or Mongol, Turkish, or European sabres is not helping so much in the cutting.
