1. Iron ore, limestone and coal to restrict contaminants. Contaminants weaken the end product.
2. Oxygen furnace is used, not Electric Arc furnace. Electric Arc furnaces permit contaminants.
3. Earth Metal microscopic structure encapsulates sulfur, eliminating layers of sulfur, which are fracture points.
4. Material-handling robots assure quality control and consistency to form and cool simultaneously in seconds, every time.
5. Coated with high-gloss enamel, which is baked to a hard finish that provides rust protection.
6. An inline oven draws each blade individually, which relieves internal stresses
and improves ductility and quality.
7. Brinell or Rockwell tests measure hardness to ensure resistance to wear.
8. Tested for elasticity under load by applying pressure to the blade—the
propensity of the blade to return to its original shape afterward is a measure
of its ability to resist impact.
