Can you use Crane Style feat line with a One-Handed Duelist?
The Feat reads: 
Crane Style (Combat, Style)
Your unarmed fighting techniques blend poise with graceful defense.
Prerequisites: Dodge, Improved Unarmed Strike, base attack bonus +2 or monk level 1st.
Benefit: You take only a –2 penalty on attack rolls for fighting defensively. While using this style and fighting defensively or using the total defense action, you gain an additional +1 dodge bonus to your Armor Class.
This is the part of the feat that my GM is looking at: Your unarmed fighting techniques blend poise with graceful defense.
So wielding one weapon can you use this line?
