Made Entirely in the U.S.A.
From the design and engineering to the forging and finishing, all work on Wright tools is performed in the United States by skilled American workers. We do not use foreign blanks or forgings. Even the steel we use is American-made.

Hot-Forge Process
Wright Tool uses four different hot-forging processes. All tools are forged using tough 4140 alloy steel. Hot-forging gives our products excellent grain flow for higher toughness, longer wear and better reliability than cold-formed tools.
