For the clip knife, having a clip to be carried top of pocket or the belt it's a Kershaw link lately. Spyderco, Benchmade & Cold Steel have served.

For the actual pocket knife, a simple 2 plus blade utility tool that lays in the bottom of my pocket there have many, including Case, Boker German Eye, Hen & Rooster, mirroring my Dad or grandpa I've carried most of them. After discovering the Victorinox brand of Swiss army knives I never looked back. I keep a backup or 2. Not gonna be without.
