Edge Stability Part 2 - Experiments

[Larrin]

In this article I summarize and analyze the "edge stability" experiments performed by Roman Landes. What results line up most closely with the edge stability theory? What surprises are found?

Very interesting. So it would seem that sometimes, less is more!

Like fewer experiments make us more confident in our original conclusions.

Hahaha! Ya, something like that!

 

[jbmonkey]

another good read Sir. thank you.

 

[Larrin]

Thanks!

I wish I could pretend to understand this. Can you put it in terms an idiot like me can understand?

 

[abbydaddy]

Thank you for sharing that, and for the work that went into it. I don't think I am ever going to fully grok the ins and outs of metallurgy and the full science of knife making, but it is certainly helpful to have data to work with if I ever decide to try.

Yeah, stop bursting bubbles with your science!

The edge stability test correlated most strongly with hardness. I then spent the rest of the article guessing about what else it shows.

I think before you diss Larrin for Part 2 you should first read part 1 like he suggests at the beginning of part 2. This is really very simple, and interesting metallurgy science, IMHO.

If simple steels show the best toughness and edge stability why do we care so much about super steels ?

^^^ exactly what I was thinking ^^^^ .

Wear resistance

 

[Revolverrodger]

Wear resistance

Perhaps wear ristance is over rated?
I use my knives mostly to cut wood (bushcraft) or meat ( hunting)
I have to say that even 420hc stays sharp quite a long time...

I think the wear resistance advantage if super steels applies mostly to industrial applications (machines that cut thousands of times per day)

I agree. I prefer a balanced steel. Vg 10, 154cm, d2, 1095 etc. I was just answering the question asked, and super steels offer better wear resistance against abrasive materials. Toughness is sacrificed depending on the exact steel.

 

[dkb45]

Were the edge stability tests ran on steels like Elmax and Cru-Wear which have reputations for being well balanced and great in most categories?

 

[Larrin]

Perhaps if I knew what a super steel is I could answer the question.

I think he means "super steel", not super steel.

Larrin - A Super Duper Steel is the one being used in today's best selling knives to aficionados of the edge. It will change with the market as I know you are well aware. It is most interesting to contemplate though and I enjoy your posts greatly. I'm still hoping to get a small laser knife with adjustable blade length and power setting. You know, the Solaris model.
