I use Harbor Freight blades. I'm lucky, when I'm in FL I live 5 minutes from a Freight Harbor. When I read about the blades on this forum I tried them immediately....then I recommendended them to my quilting group. Now they keep a healthy supply on stock and tell us to spread the word! Why sharpen when for a dollar you can have a new blade! The last time I bought them they were on sale "two in a package for $1.49". Needless to say, I stocked up!
