A Pair Decorative Knife Ends, c. 19th Cent AD
Copper alloy, each at ca. 17mm.
The one on the left features a small smiling face and looks to be wearing a turban (?). The one on the right is a claw hammer! Both have slots on the bottom.
Interesting oddities! Be sure to click the 'Images' tab for a photo as to how these would appear on a knife.
