The price of a saw is governed by its length and the qualityof steel. The following prices are approximate: Length in feet. Price per single blade. 61 8 1012 18 $ Handles. — The handles used on cross-cut saws are round,about i^ inches in diameter, and range in length from 12 to 18inches. They are fastened either by clasps which fit into holesin the ends of the saw, or by loops which fit over the ends of the WOODWORKERS TOOLS AND EQUIPMENT 75 i5aw and are tightened by a screw inside the handle. Either formpermits ready removal from the blade. Handles cost from 15to 75 cents a pair, the average price being about 25 Fig. 13. — Common Types of Cross-cut Saw Handles, a. Reversible saw handleused in the Pacific Coast forests, b. Climax pattern saw handle, c. Hoophandle. Teeth. — The teeth on a cross-cut saw are arranged in pairs,trios or quadruplets, each set of which is usually separated by acleaner or raker for removing the sawdust. Where skilful filersare not available a saw without rakers is used, the sawdust beingcarried out of the cut by the teeth. The forms of teeth preferredare as follows: yellow pine, c\press and spruce — perforatedlance teeth, arranged in sets of four (Fig. 14a); white pine, hem-lock and cedar — broad teeth in sets of two (Fig. 14b); poplarand Cottonwood — heavy solid teeth in twos (Fig. 14c); redwood-— solid lance teeth in twos (Fig. i4d); Douglas fir — soHd lanceteeth in fours (Fig. i4e); white oak — solid teeth in sets of three(Fig. i4f). The cutting teeth constitute a series
