The knife bear uses in Hawaii

 Season One, Episode Four, Bear was left to survive in the middle of an old volcanic volcano at Hawaii's Kilauea. The landscape was hostile from its ground to its atmosphere. He finally made his way to the forest; his Gerber Gator Serrater came in very handy there.

The Gerber Gator Serrater is nimble enough to be taken out in a tree top for avocado picking.
This knife is definitely recommended as a good survival knife.
