Ranking of Steels in Categories based on Edge Retention cutting 5/8" rope

Just out of curiosity Ankerson, how would 1095 or 1095 crovan rank in this list? have you had an opportunity to test them?

gomipile, ACuto + looks like 440C with a percent more moly. Phil

Alas, since 440C isn't on Ankerson's list, that doesn't help me in the context of this thread.

Thanks for spotting the alloy similarity though!

Now that you've made me spot this, I'd like to see a knife with really good geometry and excellent HT in 440C tested here, as well.

Certainly not an expert, and I'd like to see the actual test, but my WAG would be Cat 7, with a slight chance of Cat 6

You could always have one made for you by a Custom maker.

That would depend on HRC hardness so it would vary.

I am guessing folks are looking to see a shoot-out between an ESEE Izula and Becker BK11 ... and a Swamp Warden to throw SR101 into the mix ;)


How's Ankerson's health?

It looks like 440C has a fairly precise response to heat treatment, so 59-60 Rc can be obtained reliably. So, 15 thousandths thick behind the edge, at least 3 inches of straight cutting edge at 59-60Rc should be good for testing, then, then?

What knives that you have tested do you consider to have the best handle and blade shapes and grind geometry for your testing protocol?

The Spyderco Military is pretty much perfect for testing folder wise, the Demko AD-10 a step up from that.

The best are the Custom fixed blades, about 5" blade usually and thin flat grind.
 
I appreciate all of the information in this section and want to thank everyone for their input and thoughts.

Thanks-
 
Jim,
I would be interested in sending you a 440C blade to test. I flat grind to thin edges that should work for your testing. I tested them after heat treat to an average 59-60 Rockwell. Is this something you would be interested in, or is your backlog of knives too long?

No real backlog right now for this. :)

I could do it no problem.
 
Jim,

Did you end up testing the Friction Forged D2 blade? I'd love to see how it performs! Thanks again for all the testing you do!

Still working on the method to run it, it's short and thick behind the edge so it's causing me problems....

Thats to bad. Knives that are thick behind the edge belong on choppers:D. Thanks for doing your testing:thumbup:
