5160 edge retention

Thanks for posting Darrin, appreciate your perspective. As for the rest of the participants, it would be best to keep on the topic, otherwise just move it along. Personal insults and baiting comments are not going to be tolerated, maybe try proofreading before submitting. I would also wager this thread is going to get locked soon, given the way people choose to respond to one another.

Sorry rev , patience gets low. I won't continue it.

Are you able to delete posts rather than locking entire threads? I'm sure sane people would like to learn about this stuff.

This is straight from Wikipedia:

"Spring steel is a name given to a wide range of steels used widely in the manufacture of springs, prominently in Automotive and Industrial suspension applications. These steels are generally low-alloy, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant deflection or twisting."

Which is why this stuff might be advantageous when swinging into something. As for edge shaping and cutting, I don't know...

Yeah, we can trim threads to salvage discussions. It gets to be habitual with some people, and ultimately not worth it unless we are talking a page or two. It's hard to learn anything when the participants are so "knowledgeable" already and there is no room for what may be true and correct information. It would be a refreshing change to see a thread where people work together to figure something out instead of the usual insults and yelling at one another as if repeating the same thing will somehow make it truer or more correct.

I made a few 5160 test knives, found 5160 is plenty good as a knife-steel, especially when optimally heat treated. I usage experiences - in edge retention aspect - with knives in 420hc, ok - I gave my Buck 119 away.

Here is my 5160 test knife serves as performance baseline - http://imgur.com/DYN4v4v. Long over due for a handle. 12dps, 0.007" behind edge thickness. As a refresh - I just cut a bunch of catalogs & a couple hundred slashes (avg 8" length) through cardboard and whittled dried white oak board. Edge is still slice newsprint without tearing but doesn't push cut. I guess, at some point, I might micrograph this blade to see its microstructure. I am mostly pursuing blade steels with carbon mass % around 0.9-1.2 so 5160 is just a reference point for me.

I think, 5160 low cost & good weldability (low damage/brittle interface by heat) are the 2 strong points over other fancier/newer cutlery steels. As for as toughness - I am guessing - from steel designer view point. http://www.zknives.com/knives/steel...3V,5160,L6,S7&ni=,5217,838,140,571&hrn=1&gm=0
5160 doesn't has enough grain pinning particles to produces smaller grain size than other on the (linked) list. In turn, I think, 3v/s7/etc.. will have higher toughness than 5160. From endurance (low fatique) stand point, 5160 is better due to low carbide volume and smaller carbide size (for small amount of precipitated cementite & Cr7C3).

Did I miss something here or is everyone calling Duane Boris?

I don't remember Boris pushing 5160? He pushed Schrade, right?

 

[shinyedges]

They do have very similar ideology, Boris idealized Schrade and Duane buck, but the pattern of thought that they are the only one who uses knives is there, as well as the inability to listen to others and provide analogies that are not apples to apples.

Thread wasn't intended to be about names for Duane. Or about Boris. Let's just stop the bleeding here.
