Here is just one example, which isn't enough for a real conclusion, but, I gave my granddaughter a nice pair of scissors and a basket of fabric to play with, and cautioned her about using the scissors on anything but the fabric. Fast forward a few months and we were going to play with her fabric and she couldn't find her scissors and found them in the craft basket. And, then they wouldn't cut the fabric anymore. So, that is our sample of one.
