I have been reading them; even wrote about what I carry in comments to one. But I haven't done so here.
A knife is a tool in my daily work, though it takes a sharp one to skin wire properly and I am likely to go get a fresh single-edge razor for a big job.
That said, I try to keep my Kershaw assisted-open knife sharp and clean for wire-stripping; I carry it in my right front pocket and it's my "go-to" knife for most tasks.
Backup to it is a flat, springless, Japanese carpenter's knife that hides in my right rear pocket. Either one can be opened and closed with one hand, a functionality I would not care to do without.
For rougher work and plier/screwdriver tasks, I carry a Leatherman Wave in a belt pouch. With straight and serrated blades, scissors, five different screwdrivers, a saw, a file and a diamond "stone," not only is it handy for little jobs, I can use it to sharpen most blades I carry.
...But not the fine combination knife and steel rule I keep in my tiny "toolbox," a hard-sided eyeglass case that also holds a very small Leatherman tool, an led flashlight, a "coin" screwdriver, two folding screwdriver/plier tools, a flat multi-wrench/prybar and an eyeglass screwdriver. (The little knife takes a keen edge with a superfine diamond stone and is rarely used. That way, if I need a very sharp knife, I'll have one).
Rounding out the edged and other tools, a Starrett 4" pocket driver lives with the fountain pens in my purse ("green tweaker" drivers are sooo everyday!); my home and car key ring carries a small single-blade folder and my work key ring includes tiny folding scissors, useful for assembling some kinds of coaxial connectors.
Counting each bladed multitool as one "knife," that's a total of six sharp things I'm carrying any time I leave the house. It may be excessive but I find it handy -- and darn it, I still manage to break my fingernails! It seems like a lot of them are banned in one state or another; and people wonder why I'm not fond of travel.
