With me, it all depends on my main activities during a time period, or it's a seasonal matter. My default always includes a 5th pocket carry, and that depends on my main activities during that period. That rotates between a Vic Manager for ordinary out and about, and when I'm busy with hardware involved projects, a Leatherman Micra, either of them attached to a micro light. That can last weeks or months for either. The Micra is great for small mechanical or fixit projects, and sometimes larger ones. For example, it's what I use to install or remove our window air conditioners.
This is the knife I am currently carrying, replacing the Delica 4 that had been my constant companion the last 4 months, and which had been in my pocket the previous 4 months. Sometimes I carry something else as a change-up, but these are my long term users, anywhere up to a year.
