There is alot of discussion about the blades from Harbor Freight &Tool Co. Quilters are using these blades in 45mm rotary cutters, say they are sharp and work fine. Found in the stores in the carpet tools dept. Fit our regular cutters. If you have a store close go shopping or order, except there has been such a run on them by quilters they are on back order til Oct. Check these prices!
