The only thing that I have consistently carried with pocket clips are ballpoint pens, and over the years they have often suffered bent clips, been lost, and have frayed many pockets. Knives are similar, with the added negative that you end up advertising to the world that you are carrying a knife, which can be an easy to steal item of value, a politically incorrect hassle in the workplace, and perhaps an open invitation for legal harassment.
I usually carry a slip joint, or a smaller tactical folder in pocket. Anything larger than that goes into a belt pouch, jacket pocket, or similar location on a pack or fanny pack. The knife is safely carried that way, I needn’t worry about keys or pocket change damaging the knife, light detents or assisted opening exposing an edge, and it is easy to find and use even with gloved hands.
Pocket clips are a solution, but not the only solution, and for many of us far from the best.
