SO the so called Super Steel also known as Cpm steel I think. IS there any cpm or super steel which can match the toughness of 5160? and could you tell me the name of said steel.

Thank you for your time
 
Cpm 3v.

CPM is a technology, not a steel. It is an acronym for "Crucible Powder Metallurgy". Carpenter uses a similar process (CTS), and Bohler also uses a powder metallurgy process with some of their steels. As for steels tougher than 5160, as jdm61 stated, CPM 3V is a tougher steel.

Super steel is a broad term, "super" at what? Edge retention, toughness, corrosion resistance? Some examples of what are generally considered super steels would be M390, S90V, S110V, CPM-20CV, 10V, CTS-204P. But those only excel at edge retention, INFI and CPM 3V are some of the toughest steels available.

is toughness your only concern?
It is very hard to answer these open-ended questions with endless amounts of hypothetical application.
When I am testing a steel that is new to me I try to clearly defined what it is I'm trying to accomplish. After doing so I can design the type of testing I want to do and then determine if I have accomplished what I set out to or if further testing is necessary.

If you could take a little about the time and explain the ideal blade for yourself. Than I could give you some suggestions of different steels that might meet your needs.

so my ideal blade or in my case my planned custom blade is a 12 inch kukri (12 inch is for blade length) for hard use work to give you some background information and as for steel i intention for the steel is to be have excellent toughness (equal or above 5160), edge retention, strength and good wear resistance . good corrosion resistant because I live in a tropical climate Malaysia.



Edit: the use of my blade is to cut wood (soft and hard wood), cut bush (malaysian climate), do some camp chores like cutting onion, garlic and meat. I also hunt wild pigs so something that will stay sharp for butchering the pig after the hunt, my personal philosophy for a knife is to have 2 uses utility and combat so something that can be used in self defense too.

I think this one was done by one of the regulars around here (Nathan The Machinist).

Hi Logan5219. I think some of the information Dan was looking for includes, what, specifically, you would want the blade to cut/chop..... Local brush (what type), coconut, local trees (what type), fence posts, wild pigs, rusty old car doors?..... the more specific, the better. It gives the knife maker a much better idea of what your needs are. The way you cut may make a difference. Are your cuts and or chops clean and accurate, or do you often see deflection of the blade and maybe hit a few rocks - this might affect the blade grind and profile that would work best for you.

I don't know if you're familiar with Dan or Nathan. You can see in the above video what Nathan can do with steel. Dan just won the Blade Show cutting competition for the third year in a row - with a blade of his own design and making. To put it very mildly, he knows a thing or two about making an edge do what you need it to do. Mike
