I came by these at an estate sale of a retired elementary school teacher. They were still in the box and each pair of scissors is in it's own envelope. I can date these to 1967 or before as the company moved from Cambridge to Braintree in that year.
Heavy duty, industrial school supply scissors at that time were made to last daily use and abuse for many, many years. Stamped Jason on one side, Hardened Tempered on the other.
These 4 inch scissors are perfect for little hands cutting construction paper, felt, yarn and such for those all those classroom and art projects.
