An essential item for craft work and bookbinding is a stainless steel ruler to use as a cutting edge. This model has metric measurements on one side and imperial measurements on the other. Supplied in a plastic slip case for protection.
Steel rulers are sometimes made with a cork backing to prevent the ruler slipping, and you can create the same effect by sticking a length of cloth binding tape to the back of the ruler.
Available in 500mm and 600mm
