I only have the full sized model and can't compare it with his little brother...
I EDC it in my pants back pocket.
I use it daily for minor chores : opening boxes, cutting various materials...
Reactions from outsiders vary from "hey... what a great knife !" to "hey .. is not that dangerous ?" ....

I try to keep it sharp, as best as I can. It's sturdy. What more could I say .. ??... I like it and feel nake when I sometimes (not often) am without it.

Due to legal issues, the smaller RSK might be better for EDC.
