In Incised letters unnecessary junctions of the parts may be avoided (see fig. [215]). Where they are necessary, as in a capital E, or in a small y, cut [p401] away from the junction or down on to it, rather than towards it.
The Mallet-headed and wooden-handled chisels are used with the Mell for large work and for cutting surfaces. [p402]
