Federal Knife manufactures Shear Blades for just about any shear. Over the years, we have sold blades for the following shears: Piranha, Cincinnati, Niagara, Amada, Wysong, Donewell, Tennsmith, and many others. The steel content of these blades can be high carbon, high chrome for maximum wear, or a shock resistant tool steel that resists chipping for heavier applications. They carry many sizes in stock.
