Harbour Freight blades
I was so excited to try the HF blades. But was so very disappointed. They did not work at all for me. I did take them back to the store. The clerk gladly gave me a store credit of which my husband spent immediatley. I told the clerk I heard they worked in my quilt cutter. She said " oh no." I returned 3 pkgs. so I was happy she gave a credit.
