I'm like you I carry both. Especially in a large city like Colorado Springs...it's attracted more than it's fair share of unsavory types since the state legalized weed...you need to go out prepared for just about anything.
Just redneck in me.... My belt has a Bowie (10 or 12") on it nearly all the time... And I have an Arkansas Toothpick that carries down the back of my neck - Don't use that one much anymore... And a boot knife is stitched into my muks, just a little smaller than the Bowie (8"), but easier to get to with my coats on .. And my main companion knife, The one I use the most, a Schrade bushcraft knife (about a 5" blade)... That's usually on my belt too, and have an identical one rigged as a neck knife for winter too...
The knives are generally more important to me than the pistol is - They carry on my right flank... The pistol is center left in a rocker holster so I can squat down, and is set up to cross-draw, though I can get it out left handed too.
If I ain't got my rig on, I still have a big folder in my back right, a leatherman, and a penknife in my front right that is wicked sharp (slivergitter)...
Knives in this day and age are underrated.
