It s known as a low alloy steel due to the fact that it contains eight additives.
O1 steel knife.
They re so close in the chemical composition the aisi l6 is a bit higher in.
The most popular carbon knife steel is 1095.
Cpm 3v plus more advanced high speed steels like m4.
The charts below aid visualization of the strengths and weaknesses of a particular knife steel.
Some popular steels in this group include d2 o1 and crucible s cpm series i e.

O1 tool steel is a cold work steel and is one of the most forgiving for making knife blades.
The trade off is being more prone to corrosion given the low chromium content.
Thanks to johnny ngo and althesciencepal for becoming knife steel nerds patreon supporters.
O1 tool steel is the original oil hardening non shrinking tool steel that can be hardened to the rockwell c 65 range from a low austenitizing temperature.
Simply put o1 is a better choice for knife blades particularly where wear resistance is key.
The other minerals added are carbon at 0 95 silicon at 0 4 chromium at 0 5 tungsten at 0 5 vanadium.
O1 is a general purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness strength and wear resistance.
O1 tool steel knives features.
The largest additive is manganese at just 1 2.
The most well rounded steels like cpm 154 and 154cm create an even shape while a steel like cpm 3v is severe due to high toughness and lower scores in all other categories.
O1 steel was developed in 1905 by halcomb steel which was acquired by crucible steel a few years later 1 2.
Its origin traces back to the decade of 1940 and ever since it has become popular.
In all being low end tool steel and compared to its price and i find that it s worth to own make an o1 steel knife.
Unlike damascus steel blades which have a beautiful wavy pattern on them this steel only has its lustre and no pattern.
However the history is a bit more interesting than that.

High tungsten high vanadium o1 is a better steel for knife blades than o2.
Tool steel primarily hard steel alloys used in cutting tools.
O1 steel is a newer form of steel that is employed in the forging of knives and other objects.
