These, whether called firmer, paring, or mortise, are much the same thing, and between the former two the cabinet-maker need hardly distinguish, as the chief difference between them is that the paringchisel is longer than the ordinary firmer. Perhaps a better way of putting it to the novice is to say that a long firmer is a paring - chisel, or that a short paring-chisel is a firmer. The latter often have thin or bevelled edges, as in Fig. 17, instead of as shown in Fig. 18, which represents the ordinary firmers, though these are also made with bevelled edges. The number named on the list may seem a large one, and those who do not care to get them all at once may buy them separately, as required. They vary in width from \ in. to 2 ins. The most useful sizes to begin with will probably be 1/4, 3/8, 1/2, 5/8,3/4,and 1 inch, others being got as wanted. The mortise-chisel has a much thicker blade than the others, as will be seen from the side view of one in Fig. 19, and the handle is better for knocking. The most useful sizes will be 1/4,3/8, and 1/2 in. It may be well to remind the amateur that other chisels should not be knocked with hammer or mallet; and if his workroom is accessible to other members of his household, it will be better to keep his chisels locked up. The ordinary domestic, and women generally, often seem to have a difficulty in distinguishing between a screwdriver and a chisel, but with strange perversity frequently select the latter to do the work of the former in sundry household jobs, such as raising carpets, opening boxes, and so on. The chisel is not improved by such treatment, and generally wants attending to with the grindstone afterwards. N.B. - It generally seems the best chisel which is used for such purposes.
