Used to have my Leatherman Wingman clipped to my pocket for months after I got it. Carried a lot, then. SD knife, pocket knife, loaner/LM, sometimes a small gentleman knife. Still do that last one now. But, the thing is, I saw how useful the SAK was after getting my first few 91mms, and kind of fell in love. It is not that I stopped carrying the LM, I just carry it clipped in with my flashlight, 4" prybar, pens, lighter, notebook, Opinel etc, in my messenger bag, where I carry things that I like to have about, but do not want to burden my person with. It's a great way to carry things, or great to have in the car. I rec one for everybody. I prefer it to a backpack in the sub/urban enviros I live in.
I then tried to consolidate my needs into less knives. All I feel like I really need anymore, on most average days when I go out, is a SAK, model varies, 91mms for going out, 71mms for leisure. Also, about 4" of blade on, usually, a Spyderco, favoring a Police 4, Native Chief. They are great cutters, and these knives, as opposed to say, Cold Steel, or even smaller ones like my blacked-out PM2 or, re-ground Janich Endura, look less intimidating due to the color and shape. They give me probably 80% of the defensive potential as a Matriarch 2 (my former SD EDC) or any of those knives.
I will sometimes change to a more change to a smaller cutter like the Dodo (which I think is also a sleeper SD knife) or the Dragonfly if I am going out and expect a specific task. Sometimes I pick particular knives because they are nicer/fancy. Sometimes i change to a bigger/more SD oriented blade if I do not like where I have to go to complete a task, if I know there will be no cutting tasks, if I walk late at night, as I did recently due to being blessed with rain at last. Carried my Espada XL, people are crazy in the rain for some reason and we have coyotes, lost two cats to them.
