Has anyone tested the K390 mule yet for its hardness?

I doubt many people even have them in their hands yet, aside from the few people that were lucky enough to buy them in person.

Perhaps JLS or Ankerson will be able to test the K390 once they arrive and post the findings on this thread

I do keep that thread up to date both here and at Bladeforums, so if someone posts it, it'll get added to the first post. :spyder:

It's gets better? Also I got a question, I plan to give mid a vinegar bath when I get it. Will a Patina hinder performance? Thanks

You have to sharpen K390!!!! I guess it would be boring if they came out with a cutlery steel that never got dull. I have been looking forward to this mule since it was announced and can't wait to put it to use.

Sal, is it fair to say that the latest mule has the highest RC rating among the mules you made? Thanks.

There is a link, denoted by bold and underlined text, in post #3, taking you to a thread with all the known Rc results of the Mules.

Thanks ZL1 and mattman, for your replies. I wonder whether anyone had sharpened the ZDP mule? Must have been a time-consuming process.

depends on what you are sharpening with...
At some point I wanted to ask Jim (Ankerson)(?) how he sharpens and measures thickness "behind the edge"

I sharpened the ZDP-189 mule on my WEPS. It was similar to the below.
I would have run out of patience doing it with water stones. Diamonds to profile are required!!


I sharpened up one of my K390 mules today. I am using the Wickededge system. I set it at 15 degrees per side. I took a very few strokes to apex the edge with the 400 grit diamond stones.
It must be close on this one to the factory grind

Nice, hair whittling, literally, edge. Went to the Atoshi 2K and up to 0.05 diamond strops.

Real pretty, and sharp!

We will see about edge retention!


I wonder if I can find a link to how Jim sharpens for his testing!

I use the Edge Pro and Silicon Carbide Stones, 120, 320, and 400 grit.

Stones are Congress Mold Masters, pretty much all I use now normally.

For touch ups I use either a strop or ceramics.
