I do have two mini bars, but they sit in toolboxes, not in my pocket. A knife is always what I have on me, so I use it. After so many years of using tools and stuff, I figured that what I need is a knife that can do all jobs. So, a cheap, dull knife seems to suit my needs.

In the few times that I needed a razor-like sharp knife, there is a light utility or xacto knife in my bag. But that is about 1% of the time only. The dull knife does 99% of work.

One time I used the tip of the blade (part of the blade nearest to the knife tip) as a fine screwdriver to fix my wife's glasses. On another occasion, I saw an open telephone cabinet in the street and the door handle was broken, so I used the spine of my pocket knife as the tip of a large screwdriver to turn the remaining part to close the door.

Seems to me the pocket knife is more versatile than a mini bar, and will be in your pocket when you need it.
