My first set of tools were SK. In 1965 i got a job at Mel’s 66 in Quincy,IL. Mel ask if I had any tools I told him no, he told me I had to have my own tools to work at a service station. Mel bought me a small set of SK tools in the same little green box that you are giving away. He took $2.00 a week out my check until they were pay for. Those were some of the best tools I ever used.
