I bought a cutter with blade in it, removed it and placed it in my rotary cutter. (the cutter has a guard to go under the carpet and isn't usable) the price was right and it worked great. I know the company does not manufacture these for our quilting uses, but anyone that doesn't want theirs, I would be glad to buy them! My HF store does not carry the blades seperatly, so I would have to pay high shipping costs to get them. Linda
