Prometheus Dog Tag Tool
We hesitate to tell anyone to wear dog tags that they haven't earned, but respect for our military aside, the Prometheus Dog Tag Tool is useful enough for us to wear it regardless. Made in the Bay Area from titanium and stainless steel, this versatile tool offers a "universal" closed end wrench that works with both standard and metric bolts, a quarter-inch bit driver, a battery bay driver, and, of course, a bottle opener.
