I order mine online. You can get the rotary cutter that comes with 2 blades it is designed for carpet. I don't see a good application for the cutter. However, the blades fit in my rotary cutter at a fraction of the price. I have order 10 pks of 2 blades each. Even with shipping it is a fraction of the price for rotary blades at WalMart. The down side they have been on backorder for a month. Shipping should be sometime this month. Hope this helps.
