1. A model one, preferably 8 inch blade. No explanation needed for this one, I think.

2. Combat Companion, sturdy backup for the #1, many chores easier with the 5" blade.

3. The Triathlete, with or without handle material, concealable, sturdy, I love the way they feel in hand, especially with scales.

4. Don't leave home without one.
