I finally received my Harbor Freight order of blades after being on backorder for a long time. I just used one this week to cut out pieces for placemats I'm making for my daughter-in-law. The HF blade I used was SO GREAT! It cut through four layers of fabric like a hot knife through butter! I have never had an expensive blade from quilting sources cut this well. I wonder why this 'much less expensive' blade outperforms the expensive blades we've all been buying? And a good lesson to always check out hardware places!
