This vintage tiny abalone shell pocket knife fob or pendant measures only 1 1/2 inches when closed. It is functional but probably not very sharp.
One side is covered with a carved piece of colorful abalone. The other is covered with iridescent beige mother of pearl.
Made by D’Luxe, marked on the blade. It can be sharpened if desired. There is no rust and the blade is in good condition. It opens and closes well.
