I've put together a little collection of vintage French wooden pastry cutters and a couple which have a metal wheel, one a pastry cutter, the other a fabric cutter.
 
A well used domestic utensil, with all its history of use in a French home, makes a beautiful decorative piece in your home.
 
The wooden wheels all have signs of use, including splits in the wheels and measure around 5" long, they are for sale individually.
 
The metal wheels, one a pastry cutter, the other a fabric wheel are approximately 6" long and sold as a pair.
