PFAFF Expression 4
 

Can anyone tell me if it is possible to replace the small blade on my machine that cuts my thread as I am having a lot of trouble with it. Most times when I press the buttons I end up having to cut with snips and it defeats the purpose of having this on the machine.

I had problems with mine from the start. The repairman where I bought it told me to just get used to it. But after the last repair it seems to have fixed the problem.
