For packaging purposes, this blade is folded into a coiled position which is similar to a spring and may pop open when uncoiled. Wear leather gloves and eye/body protection while using extreme care when uncoiling the blade. Failure to exercise the proper care could result in serious bodily injury. See your bandsaw owner's manual for further safety instructions. Please refer to your owner's/operation manual tomake sure the blade's length, width andthickness can fit your bandsaw machine. This WoodSaver Plus band saw blade is an improved version of WoodSaver blade. The precision ground teeth have a variable 3-4 tooth design which cuts smoother, because it reduces chatter and vibration. The blade saves even more of your expensive woods being lost to sawdust. The sides of the blade are polished to provide a smoother running blade. The back of the blade is polished round to help eliminate marring of the wood. The carbide impregnated tooth technology gives the blade incredible life. The following bandsaw models use 72 inch ( 6 ft., 6' ) bandsaw blades. Shopsmith 10;
