Hi Mike,

It is not as loud as my Fox40 Micro, however it works as a compromise for me. I never used to EDC a whistle or a blade of any sorts in urban/office settings (only a keys, a photon and a Res-Q-Me previously). The SAK classic with whistle fixed both of those issues without adding any real bulk.

It seems cheap enough that if you get it and don't like it I am sure you could find a non-EDC home for it somewhere in your life.
