Nickel - Chrome alloy steel creates a stiffer, corrosion resistant blade for better cuts and longer life. It also allows for a higher Rockwell value while providing a tougher, more forgiving blade. The tips are an advanced, sub-micron grade of tungsten carbide for smoother, cooler cuts and much greater tip life. Tip life is up to 10x that of ordinary carbide saw tips.
