A mason's scutch tapers to both ends, one end being a chisel-like point and the other tapering on all four sides to a sharp point. Both ends are useful for various jobs of chipping away bricks, blocks, and stones to make them fit into the required spaces.

Made of either wood or metal, the mason's level differs from a carpenter's level in that it is usually longer, averaging 42 to 48 inches in length, or even more in some instances. It probably will have three spirit bubbles, one of which either is set permanently at a 450 angle or can be adjusted to various angles up to that. In a pinch, or for small jobs, it is possible to use a short carpenter's level, adapting it to use by binding a good straight board 42 to 48 inches in length to the side of the level, keeping the board even with its lower edge, and using masking tape or friction tape. Be sure that the board is secured to the level exactly at its bottom. This can then be used with assurance of accuracy. If, however, you plan to do much masonry work now or later, it will be to your benefit to buy a mason's level. In some narrow spaces you will need a shorter level and for this purpose a 12-inch or shorter one will do. A torpedo level (see sketch) about 9 inches long is a convenient- sized level to have. It usually contains one or two spirit bubbles in the body of the tool in addition to the central horizontal one on the top side. A line level hooks onto the mason's line when it is to be stretched tightly between corners of bricks or blocks; it is used as a guide for the line so that courses of masonry can be kept level and straight. By using such a level you can be assured that the line is stretched properly to a true level.

Plumb bobs are hung from a point on scaffolding or from a cleat on a high stake as a guide for keeping walls from bulging in or out, and for keeping corners plumb and truly vertical. Plumb bobs come in various weights, but we suggest that small ones are as accurate as large ones and are cheaper.
