[Pacific Rim] Why didn't Gipsy Danger lead with it's blades?

Kaiju Blue. Kaiju blood is incredibly acidic, and requires special containment to stop from poisoning the surrounding air and water. The general rules of engagement begin with concussive attacks (that is, generally fists), then moves on to attacks designed to cauterize (the plasma cannon, or Striker Eureka's "anti-Kaiju" missiles -- these are imperfect, but better than nothing), and only uses actual cutting attacks as a last resort. It's a containment measure. Buildings can be rebuilt, roads re-laid, but Kaiju Blue takes a long fuckin' time and a lot of very expensive resources to clean up. That they'd rather knock down a few buildings than deal with it up-front should tell you exactly *how* expensive the cleanup process is.

Crimson Typhoon's use of sawblades as a first-line attack was considered highly controversial, but the Chinese government was willing to do the cleanup, so nobody really questioned it. Other governments were more sensitive to the long-term environmental damage.
