O1 tool steel overrated?

"Most people will never see the difference because the alloy content in the steels is so close percentage wise, in steels like 1095, 1080, 1075, 01 etc.

Move into the A2, 52100 and W2 range then the difference begins to show up with the alloy content."

1095, 1080, & 1075 are not alloy steels. note the second number is "0"

They all have a percentage of alloys added to the matrix .....

If you look at the Alloy content of those steels.... ;)

HR 1075/1080
Typical Chemistry: C .70/.88 Mn .40/.90
HR 1095
Typical Chemistry: C .90/1.04 Mn .60/.90

where is the alloy? Mn is not considered an "according to Hoyle" alloying element, All steels have Manganese in them relative to the carbon and alloy content. Timken lists no "10" steels as standard alloy steels

Manganese (Mn)
• Increases hardenability, wear resistance, and tensile strength.
• Deoxidizes and degasifies to remove oxygen from molten metal.
• In larger quantities, increases hardness and brittleness.


Carbon (C)
• Increases edge retention and raises tensile strength.
• Increases hardness and improves resistance to wear and abrasion.

Silicon (Si)
• Increases strength.
• Deoxidizes and degasifies to remove oxygen from molten metal.


Without the above it would just be iron ore.......

Jim is right, o1 holds an edge much longer than 1095. I have a sunfish forge o1 blade with a covex edge and it out performs any of the commercial 1095 blades i have.
 
I'm just about to forge two kiridashi inspired knifes from O1 and two from 1095. I'll have the experience of working both steels side by side with the same pattern and HT. I should be able to feel any differences in the steels as I'm working them through the processes.
 
O1 properly heat treated is an excellent steel, properly heat treated. I have had good and bad luck with it because of HT.
 
I've had nothing but good experiences from 01. It does rust really quick, but after its 1st patina it's fine.


And it is tough, i give all my knives very thin edges and it'll chop without rolling or chipping on oaks.
