The great popularity that the Old Bear knives enjoy shows how great the customers' desire for such an original, almost archaic knife is. The Old Bear Rainbow series shows that the robust and simple technology can also be combined with a very modern design. Not only the very young knife users are happy about the rainbow-coloured handles. They also make the knife clearly visible in almost any environment and drastically reduce the risk of overlooking and losing it. The blades are made of 420.
