I use an Arc Co. - Bolder

I carry a few different cards on the inside card holder, a few bandaids of various sizes in the mini inside pocket. Then in the back card slot I keep my main credit card, and a couple ‘rewards’ cards for places I frequently go for lunch.

Then the front right pocket has a Swiss army knife (hiker) that I modified the small blade on (into a warncliff blade shape for wood carving), and the left pocket has a mini-Sharpie, and a space pen.

I just carry it in my front right pocket, it’s super compact, and has so much in it that I use everyday.

I’ve carried it everyday for over a year, and it’s still like new, incredibly well made.
