I own what the average person might describe as “a lot” of pocket knives. My Opinel No. 8 is a “desk knife.” My Böker Plus Urban Trapper is a “dress knife.” And my Spyderco Dragonfly 2 G10 is ostensibly the all-important EDC. But the “knife” I use the most isn’t actually a knife at all. That’s what makes it so useful.
Gerber Shard
The Shard is what Gerber calls its little keychain multitool, and theoretically it has seven functions. In my experience, it really has about three.

The first function is a bottle opener — always nice to have on hand. And then there’s the mediocre-but-always-handy Philips head screwdriver. On the business end is a combination wire stripper-puller, flathead driver and pry bar. Or, for most of my purposes, the knife-ish bit.
Most of my day-to-day cutting tasks barely require a “blade,” much less a sharp one.
What I’ve realized after years of poring over different types of steel and sharpening edges to the point of shaving hair is that most of my everyday “knife” tasks barely require what you might call a “blade,” much less a particularly sharp one. Breaking down cardboard boxes, ripping through plastic wrapping, scraping things off of other things — these are all jobs a sharp knife can accomplish, but are also quite suited to fairly blunt edge.
