EDC vs SD knives

[Gatorade]

After receiving my Kershaw folder from Michael I have found myself in a little Selina. Previous to this I had a couple cheap folders that I used for everything from package opening, to screw driver, to pry bar. This Kershaw is way too good for that. Now I find myself carrying the Kershaw more places but putting it to use less often due to wanting to keep it in the best shape for self defense.

This got me thinking about what factors y'all think of when looking for a daily utility knife, and what differences you look at when looking for a self defense knife. Also which would you on have in your pocket on a daily basis.
