I purchased these pinking shears for my partner for dolls house and miniature crafting i.e. cutting fabrics for making curtains, re-upholstering etc using fine fabrics and silk. The edge of the scissors are an uneven join of the 2 metals and as cutting instruments are absolutely useless. They simply do not cut but rather indent the material, they do not even fray the fabric and at best (in the words of another reviewer) "chewed" the silk.
Maybe the scissors are better for thicker, firmer fabrics? Information on the scope of use would be useful, however you expect scissors to cut. The pair we received simply did not.
One very frustrated and unhappy customer as the 1/12th silk toile de jouy is jolly expensive! We will be returning the scissors for a refund.
