The fixture comprises an articulable holding arm with at least two movable joints and an extension portion swivelly attached to one of the joints. The extension portion terminates in a holding member for the scissor or scissor element which holding member is freely concentrically rotatable relative to the longitudinal extension axis of the extension portion. The holding member comprises a clamping element for holding the scissor element parallel to the longitudinal extension axis. The extension portion further comprises a position adjustable stop to limit rotation of the holding member to provide a precise angular holding of the scissor element relative to an adjacent sharpening element.
