Replacement Cleaver Blades

Cleavers do not have “cleave counters” like a fusion splicer has  arc counts. There is no visual way to know when the blade must be turned by looking at the cleaver unless a microscope or magnifier is used to observe the edge of the blade. The numbers on the side of the blade indicates to the technician  the current position of the blade, but not how many times the blade has been rotated though all of the positions.  The manufacturer may suggest rotating the blade to the next position each time electrodes are replaced in the fusion splicer. If this is your equipment and you are the only one who uses it than this technique may work fine for you. Often however the technician is not the only one using the equipment. Perhaps he or she must wait until multiple fibers need to be re-cleaved, or bad splices must be reworked before determining the wheel must be turned or replaced. Although replacing the wheel can be done in the field successfully and without too much trouble, I prefer doing this preventative maintenance at my shop, not in the field. Cleaver blades are not that expensive when you are not purchasing from the manufacturers. Each of the big three manufacturers, Fujikura, Fitel and Sumitomo charges 2 to 3 times the cost of these equivalent quality blades. These cleaver blades are as good as what the manufacturers sell. Considering the price, they are a better bargain. FiberTool® sells the best quality replacement cleaver blades. They are the only aftermarket cleaver blades we know of manufactured in the USA. You can get these quality replacement fusion electrodes for the following manufacturers: • Alcoa Fujikura® • Sumitomo® • Fitel® • Corning® FiberTool® replacement cleaver blades last as long as the original equipment manufactured parts they replace but for 1/2 the price! Each cleaver blade meets and/or  exceeds the specifications set for the fiber optic industry. Each blade is inspected individually to ensure 100% adherence to our stringent tolerances.
