I haven't had any problems with the Harbor freight blades. I figured they were made to cut carpet they should do well with fabrics and so far they have been fine. I am sure there are bound to be some bad ones though. I bought premier blades from Amazon but haven't had a chance to use them yet. I know mine cut different on different mats and with different handles so I expect it is personal preference and a person has to try to find what works for them and their equipment.
