Coming in at just an inch long, this is the teeniest working knife and it's just as handy as it is cute! The steel blade is 3/4 inch long and sharp, so be careful while opening and closing. The blade opens and closes nice and snug so you don't ever have to worry about it accidentally opening on you. The knives are available in natural dark abalone shell with rainbow luster or natural white mother of pearl. Since shell is a natural material, the one you recieve will look slightly different but just as beautiful. The metal on the ends (bolsters) are made of brass and the knife comes on a 19 inch gold filled chain with lobster clasp.
