Call it sculpture for your wrists. Armrevolution (www.armrevolution.com), a design firm with offices in London and New York, has debuted a line of futuristic, mechanical-looking cuff links and is working on other men’s accessories that will have very little resemblance to your father’s accoutrements. The Perpetual cuff link series consists of six designs in stainless steel. Each set, priced from about $700 to $750, comes in an acrylic box with a leather traveling case. . . . John Allan, the owner of grooming clubs in New York City and Chicago that bear his name, has launched a series of razors meant to recall the details of classic American roadsters. The 63R Series razors (www.johnallans.com), priced at about $200 each, are made from zinc with a gunmetal finish. Brand creative director Samantha Choi explains that the heaviness of the zinc reduces the amount of pressure required for a shave, improving performance. She adds that the grooves on a roadster’s side panels served as a model for those on the razors’ grips.
