O1 steel can be used to make knives because of how easy it is to work with. It is easy to form as well as sharpen. The steel produces a very good edge that won’t dull easily as well. However, O1 steel can rust, and care should be taken to prevent rust. Drying and oiling the knife after use is usually sufficient. Some high-end mass-produced knives use O1 steel

O1 Steel Applications

O1 tool steel is used for applications requiring tough, rugged parts including punches, knock-out pins, cams, and of course, knife blades. Some old-time knife makers have alleged that an expertly made blade of O1 will outperform a blade made of Damascus steel.

O1 Steel Properties

O1 tool steel is cold work steel and is one of the most forgiving for making knife blades. It’s known as low alloy steel due to the fact that it contains eight additives.  The largest additive is Manganese at just 1.2%. The other minerals added are Carbon at 0.95%, Silicon at 0.4%, Chromium at 0.5%, Tungsten at 0.5%, Vanadium at 0.2%, Phosphorus at 0.3%, and Sulfur at 0.03%. In reference to the listed additives, O1 steel is in compliance with SAE J437 and J438, ASTM A681, and DIN 1.2510.
