Well...
On a typical day I have my skeletool clipped in my left pocket, and my pohl force alpha two clipped in the right. Here lately I have also carried a vic farmer in my back left pocket (not for edc but because I had a few friends that wanted to see it) and if I am out in the woods, I have my BK2/BK14 combo on a drop leg rig on my right hand thigh (not to be tacticool but because it is easier for me to reach) so, if I have not removed my alpha two (the skeletool is ALWAYS in the left hand pocket) then I will have a total of four. Not for any particular reason, as I will end up using the BK2 & BK14 for most all my bushy chores, but usually laziness is what keeps me from removing the alpha two. And that is how I carry multiple knives.
