they pull out a sword, toward the end, and start cutting up the Kaiju with one hit each and I'm like, "WHY THE HELL DIDN'T THEY PULL OUT THE SWORD SOONER?!?"

They spent the whole damn movie up to that point punching Kaiju in the face over and over and over again (and over) and the whole time this was going on, I was thinking to myself, "Okay, punching them in the face obviously isn't effective, like, at all... what they need is an edged weapon..." so when it turned out that they had a sword all along, and they just didn't use it because... um... because why? I don't know why... words fail me... hand meet face... (Now I know how the Kaiju feel;

Hmm... now that I think about it, maybe that was their secret strategy! All the Kaiju will facepalm themselves to death!)

Seriously, though, it really is stupid that they would do anything other than use every weapon at their disposal when you consider that: 1) These robots are incredibly difficult to build and cost billions of dollars each so it really is best to kill the Kaiju fast before they can do any damage, especially since... 2) The Jaeger program is being scrapped and so these things are completely irreplaceable! 3) Millions, if not billions, of lives are at stake; are you really going to mess around, punching things in the face when you have a frikkin' sword you could use instead? 4) perhaps most importantly, swords are just cooler.

(And it stands to reason that a giant sword would be... er... gigantically cooler!)
