Gingher blades are superior to most rotary blade. I learned to take extra care when I started using Gingher blades, they cost more then the other blades so I made myself be more careful how I treated them. No more slivers off the ruler and making sure there was no pins at all under the fabric. LOL. I bought five at a time and still have three left from my first order. Dated 2003. Good stuff lasts with care.
