Just a simple survey. Why do you carry a whistle for EDC. I"m not targeting, yet not excluding the people whom travel distances daily or why we carry one in our kits/packs, but the average person, going from home to local stores, work etc. What whistle do you prefer, and why do you carry it. I fully understand and agree with all uses for them (one on my keyring and in my pack here at work as i write this), but would like to see rationales for ones "daily carry". I figure this could also serve to help instruct our orientees as to why we carry specific daily/survival items.
