The Mares Smarty Multitool is made of stainless steel coated with a PVD treatment. It includes, among other features, a 4 Allen key for regulator plugs, a 13 and 14 mm open-end wrench for hoses, not to mention the essential bottle opener to avoid dying of thirst! Its design is very sophisticated, as expected from Mares! And it remains compact (9.5 cm) to always be within reach.
