Article: What is Edge Stability?

[Larrin]

New article on edge stability, a term defined by Roman Landes. I answer questions such as:

Just what is it?
How was the property determined?
What steel properties affect edge stability?
How does edge geometry affect edge stability?

I don't always have the time to read all your articles but I very much appreciate you taking the time to educate us. I'll get to them all eventually.

Great research, thank you.

I read through it a few times and appreciate the testing.

How about today?

Thanks for this article .It s good to read all related with knives in one place
Somewhere I read this from Roman Landes ...... if you double the thickness behind the edge you have FOUR time stronger edge .....

I read them as soon as they come out. Thanks for yet another good one, Larrin. Very good info in there.

Another excellent article. I’m really enjoying these.

great article! thank you very much, and thanks to Roman as well.
I couldn't find other informations about the Rockwell adaptation you quoted. Do you know if that method uses the comparator 10kg mark alone or a sensitive scale is added for repeatability? Roman's Vickers jig looks like quite reliable, but i have got just a Rockwell to play with

E-mail me and I will send you the thesis.

Thanks for the info I read through it once probabaly gonna need a second read for me. Not sure I understood he PM steel talk about cracking. Are you talking about tiny micro cracks in the sharpened edge/secondary bevel which can result in chipping out? CPM3V is a steel I just started to use so trying to understand it a bit better compared to say AEB-L.

It probably wasn't explained thoroughly enough because it was a condensed version of the linked chipping article: https://knifesteelnerds.com/2018/05/28/chipping-of-edges/
