Small part, big effect: Knog has redesigned its popular Oi bell and equipped it with a new mechanism. The spring has been moved inwards, the lever has become longer, is now made of elastic, nylon-reinforced material and, when activated, hurls the metal clapper at the sound body with a vengeance. Knog promises 80 decibels. Available in various diameters and colours. Cost: 30 euros.
