I use these blades and have not noticed any difference. I feel if they are sharp enough for carpet cutting they are sharp enough for fabric. However I am having a hard time getting them, it seems that every time I check they are completely out. I tried ordering them through the store but they tell me they don't have enough man power to call me when they come in. How have others been able to get them, I only have one HF in my area.
