Historically, these sets were manufactured for the Craftsman brand by Western Forge (denoted by the "WF" code on the packaging or tools). This specific set was MADE IN THE USA. Western Forge ceased supplying Craftsman tools around 2019 after Stanley Black & Decker acquired the brand and moved most production to global materials or offshore factories. As "New Old Stock" (NOS) in its original packaging, this set is collectible to those who prefer older USA-made Craftsman tools. THIS SET HAS BEEN DISCONTINUED AND GENERALLY CAN NOT BE FOUND IN RETAIL STORES.
