The tiniest hammer I have ever seen. The striking face is 6mm by 6mm on one side and 2mm by 6mm on the other. The entire weight of the hammer including handle is about 25 grams. The length is 15.5 cm.
The handle has been fixed by inserting a wedge. The handle has had many coats of linseed oil. This can be used to work on the most delicate fragile pieces.
