"TOOT TOOT"
Thats what a super-light Titanium EDC whistle sounds like. You may not need a whistle as a part of your Everyday Carry during the work-week. But they are nice to have for your weekend-adventure EDC. It attaches literally anywhere with the built in key ring hole. Wear it around your neck or clip one to a pack. Maybe you want to attach it to your keys or toss one in a survival kit.
