Years ago - way back in the dark ages (30 yrs ago), I worked at JoAnn's. The Fiskars were used to cut fabric, and they were the ones that got dull the quickest. I also don't like them because the blades are thicker. I do know that Fiskars have a style that has a thinner blade now and things may have changed over the years.
I enjoy going to the big quilt shows like the International show in Cinti where there are vendors and there are samples to try in order to get the right fit. Havel was at the Cinti quilt show last April.
