Is a katana samurai sword a primary or secondary weopon?

Answer 1

The katana is with out a doubt the primary weapon. The wakizashi was the secondary weapon.

But not necessarily. It depends on the era your talking about. If you mean prior the the 1600's during the warring states era, then the katana would be a secondary weapon. The primary being a bow, naginata, spear, or even a firearm depending on the time & the individual. Durring the Edo period, then yes the katana became more of a primary weapon, since there were virtually no more wars.
