I never had "good" scissors to worry too much about while the boys were little. I did have several "ok" pairs that I would write the date on the outside of the blades. If the scissors were over 6 months old, they could use them as they wanted.
Once I did have "good" scissors I kept them in my sewing desk that was way tooo scary to open for the faint of heart.
My DH recently saw my applique scissors and wanted to know what they were for. I showed him where in 1990 they cost $35 and wondered what they would go for in today's market. He swallowed and suggested that they be kept hid from others and only used for special projects, lol.
Now I use a rotary cutter and don't worry too much about scissors as they are basically for threads.
