Query: Won't cut a diaper

These scissors won't cut a diaper and do not cut plastic much heavier. Not so great on cardboard boxes either. I bought some for myself and some as gifts based on the reviews here and was extremely disappointed. I did find they cut plastic packaging pretty well but find it ironic they were packed in this awful stuff. Anyway, I think they work fine on paper and may be good with fabric, but heavy cutting or even light cutting with plastic (a baby diaper, I just don't get why they won't cut this) is a real chore and not worth it. Fortunately, I did not invest in the their cordless saw after seeing the poor reviews on that item, and I hope others will not expect much of these scissors either.
