I am familiar with the complaint that the Katana is not a good sword. However, such a complaint seems to be born from socio-cultural matters rather than the practicality of the sword itself, as per my observations at least. The Samurai, in their prime, didn't become such formidable swordsmen, perhaps the greatest on the planet during their time, from wielding "terrible" swords. It was an instrument that had to be "levered"; its fighting pattern unique and intricate---you can't really just swing it around, there's a whole martial art behind it.
Personally speaking, I'm more of a fan of the bow (especially since I'm Hindu). You see, archery was my first love. There is nothing like the slight creaking of laminated limbs on a traditional bow with a wooden arrow, as opposed to a carbon arrow, nocked on the string, pulled back, then released; and feeling the quick gush of wind as the feathers fly away and your drawing hand abruptly comes back. It's practically magical.
