The listing, Finger Knife has ended.
To be honest I'm not really sure what to call this one other than a finger knife.. It's solid steel with three cutouts in it. One is for your finger, one I am guessing is for a necklace/lanyard and I'm not sure what the other is for. It comes with it's own sheath, the sheath appears to be leather but could be faux leather. It measures in at about 2 and 1/4 inches overall and the blade "edged" rather than sharp. Though if you know how to sharpen knives that shouldn't be a problem. There are no markings on the knife to indicate where it was made or who made it.
