The L.S. Starrett Company was founded by Laroy Sunderland Starrett in 1880 who had patented the first combination square in 1878. Since then, we've been following in his footsteps, creating the kind of precision tools, gages and instruments that have made the name "Starrett" synonymous with "innovation". Laroy Starrett set very high standards and we steadfastly maintain them today.
