I'm going to go out on a limb and say that 1/8" 154CM is definitely not flexible. I definitely like the BD though. I've been wanting something on some leaner stock.
I just had a tomato, half an onion, a clove of garlic, 2 big brocolli stalks, spinach, a can of atlantic salmon, apple cider vinegar, olive oil, and some habanero sauce. all cut up with a spyderco yang. I love that blade!
