Work with a cutting tool and at the same time keep both hands free? Surely not possible you say. But it is! The Secumax Ring Knife MDP is worn on the top side of your finger. It can be used to cut film, yarn, thread and much much more. And if you drop it or lose it anytime, don't worry: it's made of a metal detectable plastic. Detectabilitiy minimises the risk of your safety knife landing in your production line.
