Just be sure to change blades out when you are having to push down harder to get them to work. This is the time when nasty accidents happen and a trip to the emergency room is in order. I'd much rather change a blade out for $5 than waste all that fabric money on medical bills. The pain and suffering are not worth it.
We all tend to try to save money these days. But we waste time and money when we don't take the time to change things like rotary cutter blades and putting a new needle in every 6-8 hours of sewing.
