I use a sog auto clip as my every day carry pocket knife. The adjustable clip ensures that it stays securely clipped to my pocket until I need it. Since I wear suits most days, I prefer a knife that is light weight and clips on without causing wear and tear on expensive suit pants.
Adjust the auto clip to loose setting, slide into pocket with clip sticking out, then adjust the auto clip to tight setting. The knife with stay clipped in my pocket and not accidentally fall out when sitting down.
