Even tho the HF blades are on backorder online, if you call your local store and give them the item #97642, if they have some coming in a delivery, they might hold some for you until you can come pick them up. Our store did that for me. She told me they would be in Weds. evening, so if I would call before closing Weds. nite, they would hold them for me. They had to be delivered to the store before they can hold them. So I called back Weds. nite, and put 20 on hold, which I picked up today!!! But I have been using one of the 3 blades I got week before last in the package with the cutter for $3.99, since I bought it and it is still sharp and cutting well. I only need to go over it more than once if I have more than 4 layers or if the fabric is thick like flannel or corduroy and more than 2 layers. And that is only now in the last couple days. When it was new, it easily cut thru 8 layers of cotton in one cut.
