I acknowledge a multitool has its merits, but I still wouldn't carry it everyday. Maybe if I was a firefighter or working in maintenance or something like that, but not all the time. Most of the items I listed I do carry everyday. The folding scissors and Sliver Grippers are on my keychain along with a Fox-40 whistle and Photon II. The p51 is in my wallet and the Spyderco Delica is on my waistband and doesn't show.

As for using the multitool saw in the woods, say in a winter setting the cold would catch you. Say you're wearing a parka, you have to remove your mitts, grab it from the sheath (unless you carry it on your neck) open the tiny saw in the bitter cold, be careful not to drop it in deep snow and so on, it's out of the question.
