Being able to sharpen your gravers is key to engraving because it is next to impossible to engrave on steel unless your tools are both the correct shape and sharp. You need to sharpen gravers frequently because they wear quite quickly when cutting steel, and its very easy to break off the point, especially when you are beginning. So learning to sharpen your tools is a necessary first step to engraving, even if you buy a ready sharpened tool. An experienced engraver will probably be able to sharpen his gravers freehand, but that comes with years of experience, even so, many chose to use a jig. Beginners and journeymen certainly need to use a jig in order to ensure consistency and minimise the amount taken off the tool surface with each sharpening. For convenience I have a carousel of gravers, mostly sharpened the same, so that I can change gravers quickly to continue working, and then have a sharpening session when I’ve exhausted my supply.
