Powdered Steels are high alloy, stainless steels that have been ground into a highly-refined powder form and then sintered back together. This specialized process creates a more uniform grain structure in the steel, resulting in a product that exhibits exceptional edge retention and hardness.
These steels provide the combined benefit of rust-resistance and exceptional sharpness, however they require more effort to sharpen than their high carbon equivalents, and are less durable than stainless steels due to their hardness.
