Actually no...it's not.
The composition of the weapon is not really a major factor.
What is the major factor is the skill of the person weilding the weapon.
A skilled swordsman, armed with a wooden training sword will beat an average one armed with a metal sword.
One of the most famous examples of this goes back to early 17th centuary Japan and its most famous Samurai, Musashi. He engaged in a duel against a highly skilled swordsman armed with just a wooden Bokken [Katana like sword] and defeated his oppenent in a matter of seconds.
from wikipedia:
[color=blue:24c9etrw]In April 13, 1612, Musashi (about age 30) fought his most famous duel, with Sasaki KojirÅ, who wielded a [b:24c9etrw]nodachi.[/b:24c9etrw] Musashi came late and unkempt to the appointed place — the remote island of Funajima, north of Kokura. The duel was short. [b:24c9etrw][u:24c9etrw]Musashi killed his opponent with a bokken that he had carved from an oar while traveling to the island[/u:24c9etrw] [/b:24c9etrw]. Musashi fashioned it to be longer than the nodachi, making it closer to a modern suburito.
Musashi's late arrival is controversial. Sasaki's outraged supporters thought it was dishonorable and disrespectful while Musashi's supporters thought it was a fair way to unnerve his opponent. Another theory is that Musashi timed the hour of his arrival to match the turning of the tide. The tide carried him to the island. After his victory, Musashi immediately jumped back in his boat and his flight from Sasaki's vengeful allies was helped by the turning of the tide. Another theory states he waited for the sun to get in the right position. After he dodged a blow Sasaki was blinded by the sun. He briefly established a fencing school that same year[/color:24c9etrw]."
So there you have it: wooden sword defeats metal.
Also, assuming that you will win just because you have a metal weapon while your opponent weilds a wooden one is dangerous and smacks of overconfidence. Always regard any weapon in your enemy's hand to be lethal and never underestitmate your opponent. Focus on your on training and methods and watch and wait for an openning in which to land a critical strike.
It's not the quality of the tool so much but the experience of the workman behind the tool which matters most
