Rant- no baseline on steel comparison charts.

I like researching knife steels and I come across a lot of charts that compare the relative toughness, wear resistance, etc of the various offerings. The problem is I generally are unfamiliar with all the steels on the chart. Which makes the data if not useless at least less informative than I I would like. That's why I think they should include 1095 on all charts. Then I would know what i was looking at cause I know 1095. And I imagine you would have to go pretty far to find somebody that is interested in knives that doesn't know 1095. To get where your going you got to know where you start.
 
Lots of steel comparison charts are a bit nonsensical. They all too often don't label either axis, or will give you numbers without any explanation of what the numbers are or what they mean. I find the data sheets put out by the steel manufacturers are often more helpful, as they'll usually give various information about wear resistance, often Charpy testing numbers and even corrosion testing data. I still take them with a grain of salt (they're trying to sell the steel, after all), but I think they're more reliable and readable than most internet steel charts.

In before the know it alls! err i mean experts with extensive scientific data through rigorous testing above all others.



To remain on topic i refuse to study charts. I simply cant make sense of any of it. And i can openly admit that even if i could that it would still be meaningless to me. I have owned many super steels and cheap steels. Of the dozens i have owned i think maybe one or twomexhibited traits i could single out as being unique. That is not a slight to those who can. I just dont use my knives rigorously enough to have steel charts mean anything to me. Oddly enough even though i couldnt articulate the differences beteen 8cr14mov and s30v i still prefer owning premium steels even though it is based on nothing.

I have found Spyderco's steel charts to be great.

Plus they update it every other year.

It is available as a webpage or .PDF document too.

Because there is no baseline. Not all 1095 is the same, the chemical makeup simply falls within certain criteria. Not all HT is the same, 1095 is probably the king of multiple HT recipes.

That is why a comparison is used, & not absolute values.
 
Lots of stuff we metallurgists give to you are Guidlines NOT absolutes !! I never did find tables to follow real world experience in various applications . But I knew they wer guidlines so I didn't freakout !!

Most of them aren't for knife blades anyway so that makes since.

Why I don't normally pay them much attention other than a general overview.

:thumbup: MatWeb lists DuraTech 20CV as "an excellent steel for plastic injection feed screws, barrel liners, screw tips, and mold cavities, especially for plastic resins which contain abrasive fill"

...but we know 20CV makes a pretty wonderful blade too :)
