Sorry I didn't see your comment on the Accuquilt die blades needing sharpening. Some specialty paper is made with clay that can dull blades (which is why they caution you not to cut paper with your fabric shears). I had a semi professional paper business. I have some dies that I have used thousands of times, often with clay coat paper, and none of them are dull. The hardened steel is not like a rotary blade! Cutting fabric is not going to dull them.
