Abstract: A method of manufacturing a writing implement mechanism that includes a tubular element. The tubular element has a central axis and includes a first wall and a second wall which are fixed relative to each other. The second wall is offset towards the central axis relative to the first wall in a direction that is radial relative to the central axis. The first wall presents a first edge and the second wall presents a second edge. The first and second edges define a guide extending longitudinally between a first end and a second end in a direction that is inclined relative to the central axis. The method includes the steps of supplying at least two half-shells adapted to form the first edge and outside portions of the walls.

Abstract: A writing instrument, which has an inner and outer writing element with separate writing medium reservoirs. The writing elements are coaxially mounted in an outer barrel and axially moveable with respect to one another. A driving mechanism may be actuated to allow a user to selectively extend one writing element. The inner and outer writing elements may have an inner sleeve therebetween to improve, for instance, rigidity of the outer writing element and to prevent contamination of the writing medium reservoirs. An outer sleeve may also be provided over the outer writing element. The outer sleeve can function to hold various components of the outer writing element together, and to allow for clean and easy refill of the outer writing element, especially when the outer writing element is a nib-type writing element with a filler-type reservoir. The writing instrument is designed so that a user can replace the inner and/or outer writing elements when their respective writing medium have been expended.
