A little brass fish conceals a teeny tiny, but extra sharp knife!
The tiniest of pocketknives comes in handy in daily life.  I've sharpened the blade to be razor sharp and it easily cuts paper and other small stuff.  The steel blade folds back inside the brass fish body.  Opened it measures about 2" long (52mm).  Closed it measures about 1.25" long (34mm).
It hangs on a soldered sterling loop on a just under 20" stainless steel chain that closes with a lobster clasp,
Comes in a little gift box, perfect for gifting
