(3) Throw-away type blade (Easily replaceable blades have 8 cutting edges):
The Model CE 16SA, on the other hand, utilizes a throw-away blade system that eliminates the bothersome
and time-consuming regrinding of blades. When the edge of the blade becomes worn or damaged, simply
rotate the blade unit 90˚ to expose a sharp, new cutting edge. In addition, the reversible blade units utilized on
the Model CE 16SA have a total of 8 usable cutting edges - 4 on the front, and 4 on the back. As a single
cutting edge is capable of cutting approximately 400 meters of 1.6 mm [1/16"] mild steel plate, one blade unit
permits cutting of up to 3,200 meters (10,480 feet). While B utilizes a throw-away type blade, it has only 4
usable cutting edges.
The blade types and specifications of various makers and models are shown in the table below.
