After watching 127 hours, I knew I needed a survival knife every time I go outside of the city.
Make fun of me all you want, knives enthusiasts, but the Bear Grylls Ultimate Pro knife is still a feel good buy for me
Aside from the full tang with a hammer on its butt and a really grippy handle, you've got on the sheath a Fire starter, sharpener, whistle, "survival guide booklet"
Price point (bought it at $100 seven years ago) was great for me too
