This double olive bit is an alloy of copper (60%) and stainless steel (40%). It provides a rather gentle action and presents no risk of pinching the commissures. The effect of the hand action is more direct. The double joint provides greater force on the corners of the mouth, for greater precision. This alloy is rust-proof, tastes good and warms up quickly.Composition: 60% copper, 40% stainless steelThickness: 17mmStainless steel ringsDouble joint
