Collect 5 Extra Sharp Daggermaw Teeth.
It's nice that you've been helping out Toshley and his scientists. I, however, do not have the luxury of indulging in my 'personal' interests.
If you want to make a difference around here, you'll do what I ask of you, and right now, I need weapons.
Our guns are effective at range, but when the bugs get in close, we need to have powerful melee weapons as a backup.
The teeth of the daggermaw lashtails in the northern part of the Razor Ridge make for great vibro-weapon blades. Scare me up some.
