The original Zona Razor Saws were made back in the 1950s by a company in Arizona (hence the name Zona). Zona’s production moved to California and was acquired in the late 90s by Blackstone Industries of Bethel, CT. The acquisition was a good fit since Olson Saw Co. a brand of Blackstone Industries was already making the blades for Zonas razor saws. Since joining Blackstone, Zona has expanded its line of razor saws and added small hand tools for hobbyists, model builders, artisans, craftspeople, furniture makers, and do-it-yourselfers.
