During the 18th and 19th century most adults would have a small pocket knife. This would be used for anything from aiding needlework to peeling a piece of fruit.
 
The fashion in the 19th century was for mother of pearl, this was used to decorate anything from a small sewing tool to an elaborate piece of furniture. These three pocket knives would probably been part of a sewing set for the lady of the house, with tiny retractable blades they could be used for all manner of small tasks. They would have been the property of a reasonably well off lady.
 
The mother of pearl is in very good condition with no cracks or breaks and steel blades all retract well.
