Steels are great for touching-up edges.
I have steels from Boker and Henckels and a pocket steel from Victorinox, The boker is a bit rougher than the Henckels, the Vic is fine and very portable, years ago I bought an ice-pick-like tool design for leather work (sorry don´t know the name in English) and I use it as a smooth steel, it works OK, in a pinch I´ll use the spine of another knife.
I have a ceramic steel that does a bit more than just realign the edge, I don´t use it much because I have a good set of hones from very coarse to extra fine.
For stropping I have an old Dubl Duck barber strop, I often use an old belt, my jeans (all worn out and patched on the thighs above the knees), cardboard, folded newspaper, or paper wrapped around a steel or around a hone, whatever is available when I need it.
