A nest of scissors stood out among the baskets on the market stall. There were hundreds of them, there for everyone to see. The metallic sheen of their steel was quite beautiful. Scissors are a tool with a simple and effective mechanism. They can be found in kitchens, offices, hairdressers, and sewing workshops, and are used by gardeners and surgeons. Just one small thing you have to remember about them – once you start using scissors on something there’s no going back.
