Grand Unified Edge Test Chart?

[Geneh2001]

I’m looking for a set of data where we can see edge test results from various sources in a table, sort of like a Grand Unified Grit Chart. It would be interesting to compare various peoples results by steel type. Some folks cut rope, some cardboard, others automated machines, and I would love to see all this info cross-referenced,

Do we know anyone who has already done this?

Something like this?

^^Does anyone know (maybe you do, Bob) where LC200N would land on that chart? Just curious.

 

[Bob Denman]

I have no practical experience with that particular flavor... sorry!

I never tire of looking at that chart.

Well in this chart, LC200N has toughness of 8,5 and edge retention is 3.

Kind of confusing..

The chart I posted is from your link, or a link within the link. It's Larrins.

This might just be the best data set that fits the bill: https://knifesteelnerds.com/2021/10...ness-edge-retention-and-corrosion-resistance/

Ok, this thread is like a party where everyone is talking and no one is listening to what the others say

My guess is around 14C28N. Maybe 14C28N would be a slight bit higher due to more carbide volume.

I don’t think anyone has said this yet so I will ()
http://knifesteelnerds.com/ is one of the best places to find all sorts of metallurgy and testing info!

That's not a party. It's called The Internet.

Yup!

Not trying to be duplicative, but this particular article by Larrin Thomas is probably the best guide to knife steels you're going to find anywhere:
