The Broad-webbed Bow-saw is shown in Fig. 38. Itsblade is 1 to 1J inches broad. It is usedin numerous cases, e.g., in sawing off longslips of wood, where a straight cut is allthat is required. It has 4 to 5 teethper inch. B. The Turn-saw (Fig. 40). The frameresembles the preceding, but the blade isvery narrow—about J inch, or very littlemore—^because it is used to produce cur-vilinear cuts.
