I guess I must fall into that younger group that uses a pocket clip knife. I never go anywhere without one. Like Leroy Jethro Gibbs says, Rule #9.
I've disliked heavy stuff hanging in the bottom of a pocket, change, keys or knives. So I use a clip knife in my back right pocket, easy to get to with strong hand and it must be sharp and open quickly with one hand. Also ride low in the pocket and the clip tight so it won't snag sitting down. And I use it many times a day.
Oh, I also have regular pocket knives from Dad and Grandad, Case, Barlow, Swiss, butterfly from overseas duty, and even my orange switchblade jump knife with the paracord cutter.
Have one also the twin of 'eveled' showed above.
Right now I'm carrying this one but am hoping for a SOG or Spyderco this Christmas
