You will find other threads on here about Harbor Freight cutting blades. There are different opinions. I bought 12 blades and not one would cut fabric. I have been using one to cut paper. Other people say they are the best thing going. I tried all of the tricks they suggested, cutting on a hard surface, new mat, cleaning off the oil, etc etc. If you do a search under Harbor Freight you will find every opinion/solution possible. Happy reading.
