I've always liked pocket knives (my grandfather was in the cutlery business). For about 30 years, I carried a Buck 501 Squire. Then, somewhere, I learned about Benchmade and their Griptilian knives. The one-hand opening and terrific blades on their knives sold me and for the last 10 years or so, I've carried a Mini-Grip. I've also got a few fixed blade knives stashed in packs in our vehicles - Mora, and Fallkniven (F1). The most useful knives I own are a wide variety of SAKs in various forms. Along with my Mini-Grip, I daily carry a Victorinox Ambassador which has a little blade, scissors, nail file, tweezers, and toothpick. I've carried a Victorinox (used to be the Classic) for over 45 years in concert with something else.
