Heavy Leather NYC is a hand-crafted leather goods company founded by Rachael Becker, who began making custom guitar straps for friends in the New York City rock scene in 2008. The brand operates as a small in-house workshop split between New York City and Los Angeles, with larger runs produced by a family-run factory. Its catalog centers on rock and heavy metal-styled guitar straps, alongside belts, harnesses, keychains, camera straps, and vegan-leather alternatives, with custom embroidery, engraving, stamping, and dyeing offered as part of the build process.

The brand is best known for studded, concho-laden, and embossed leather guitar straps drawing from classic hard rock and metal iconography.
