If you've escaped hundreds of times, the Chicken Knife is clearly ideal.
Also, the Brave Blade adds +5 Strength, while the Chicken Knife adds +5 Agility. These bonuses are independent of the variable battle powers, and don't change with escapes.
The Chicken Knife will force an escape roughly 25% of the time.
