In the late 60's and early 70's, the demand for stamping tools reached a frenzied level. This created an opportunity for some new stamping tool manufacturers to be born. One of these companies was Basic Tool Co. They produced stamps under the name Basic Tool USA and Basic Tool L.A. to fill the demands of the time.
