I thought it was just me being careless. I've noticed a decline in quality too. I accidentally got several packets mixed up and used the newest blades first then went back to the older packet. The older ones lasted longer and didn't get those irritating nicks that leave just a thread or two uncut. Does anyone know if the company out of the midwest that sharpened blades is still around? I can't remember the name, but they did a fabulous job.
