Lon, i EDC a whistle because i work as a machinist and it can be a very LOUD environment. Also frequently work in the back of the shop where no one else is near and yelling at the boss doesn't always get his attention. Blowing a whistle in the shop gets attention.

Back to the original question, Streamlight Strion left rear pocket, Leatherman on belt, Benchmade Griptilian on right front pocket, whistle in watch pocket along side of Arc AAA, and bandana left rear pocket.
