Cling’s Mag Grab Mini is a milled block of anodized aircraft-grade aluminum, 1.5 inches square, holding a neodymium magnet strong enough for a dozen flies or a pair of forceps, yet gentle enough to release a barbless hook one-handed. A separate stainless plate sandwiches a shirt, vest, or pack strap against the magnet to hold it in place. Off the water, it’s just as good at catching stray screws mid-repair.
