I've carried a knife of one sort or another pretty much everyday since I was 7-8 years old. Traditionals were it for many years until as an adult the modern "tactical" renditions began to replace those older styled slip joints. Today I have many of the "black majic tactical" models with G-10, micarta, ect...wonderful steels which reportedly don't rust and hold an edge forever, locking mechanisms which boggle the mind. Axis Lock, Liner Lock, Compression Lock, Rolling Lock, Integral Lock, heck some that open automatically (they used to call them "switchblades"!) They are truly wonderful users.
However, they lack one thing-character or "soul" for lack of a better word. My taste are swinging back toward my beginnings. Today, while I still use plenty of "tactical" type knives clipped in a pocket somewhere, theres always a classic slipjoint riding in the left front pocket. Give me a stag handle or jigged bone and carbon steel blades in a classic slip joint pattern and that knife seems to speak to me. It has a depth the other styles can't match. Moore Maker, Schatt & Morgan, Queen, ect...are names that are becoming more common in the knife safe. I'd love to find a dealer who handles the Marbles classic series pocket knives. Stag handles and carbon steel.....yeah man!
