Heavy-Use Steel

I don't have a whole lot of steel experience but what I know is that the heat treat tends to be more important than the actual material.
Stuff that I know to be really tough is 5160, 1095, and 52100
 
Find a knife with 5160 steel, 1095 steel or 440C steel..... Must have Conves grind....I prefer 5160 based Khukuri for mighty jobs

OK........If your really taking a trip to hell and back, 3V will break or chip. Try to buy a full tang fixed out of S5, or CPM 1V.

What is your experience with those steels and at what blade length, steel thickness ? :confused:

DC
 
S5 and S7 are used for jackhammer bits......idk how 3V would do against concrete let alone something harder in hell.

Last I checked, jackhammer bits had a bit more steel behind the edge than a knife blade. So without a 3V jackhammer bit to compare with, that sentence really doesn't mean much.

And its "harder than" by the way. :thumbup:

You make me want one of your knifes more with every one of your comments:D
Was that the right little face for sarcasm?
 
S5, L6, 3V....in that order . OP's thread needs are very clear. It's not about maintaining an edge for cutting cardboard or paper or rope.

I'm looking for a blade steel that can be put through hell keeping its edge, and of course without breaking.

Look at the opening post; he does want edge retention.

FFK said:
No 3V jackhammer bolts.....ah duh....wonder why ?

Because the requirements for a knife are different than the requirements for a jackhammer.
Or a shovel.
Or a hammer, etc.

There's a reason more than one type of steel is produced.
 
Look at where OP wants to take/use knife. Edge retention will be the least of his worries.

Dear God, he was using a metaphor. :rolleyes:

If you seriously thought he was looking for a physical knife to take to realm of eternal damnation, then dude, there's no hope for you.
 
Stabman,
Mine was a metaphor also......goes both ways.....take a chill pill

Think S5 at 58-60RC could handle the 20 degree edge.

Inclusive or 20 degrees per side? It hardens up to rc 62 unlike S7.

Still would like to know about the 1V knives you have made. What kind of results do you get. What do you run them at?
 
Pretty much any modern steel with a decent heat treat can be a "hard use knife" if you make it thick and obtuse. Geometry is king. However if you want it to cut well and be tough it starts being more limited...

So you don't EDC a jackhammer? ;)
