On a popular Reddit.com forum called “Buy it for Life,” a community of consumers extol the virtues of Methuselah-grade toasters and table saws, and lionize brands like Blundstone (boots), Bushnell (binoculars), Craftsman (tools), Vitamix (blenders) and Briggs & Riley (suitcases) for creating truly durable goods—and standing behind them.
First time seeing Methuselah being used as an adjective. Wasn't searching for it.
