Re: M398 Edge Stability Test
Hi Bluntcut,
Thanx for posting the video. Is that you doing the tests? Who made the knife? Hardness?

Hi Sal,
I ht and made and tested this m398 knife. 10 hardness readings (before putting on the handle) between 64-65rc. Desert Ironwood handle.
It's just one of many steels I am testing in this batch of experimental ht:
Luong/bluntcut.

There are days like this, when I see all of those knives, that I wish that I made them as well.

Thanks for posting that!
And I agree with Naperville. Scales and handles have made me want to move on to making blades, for sure.

Howdy Luong,
Nice job on the m398. I figure if anyone could make a glass blade chopper, it would be you. :)
All your knives of mine are doing well except the zwear. It's had the tip broke, edge trashed, and left submerged under water overnight several times. I've repaired it a few times. It remains the girls' favorite knife in the kitchen and elsewhere. They're very rough on it. :)
My favorite is the m2 at 66hrc? It has the thinnest and most stable edge of all.
Take care.

Re: M398 Edge Stability Test
Hi J.
Thanks. I found this M398 tougher than my previous ht m390 at 64rc. It has wider range of plasticity (i.e. will micro roll).
Sorry about the broken tip. I prefer (ok, bad habit of) fine/delicate tip... don't recall whether your zwear blade tip is thin or ht wasn't as good.
I agree, M2 66rc is very stable. I still have a few m2 blades are waiting (dust collecting) for handle. And still has quire a few bars of m2 onhand. M2 fine/small carbide is nice for shaping keen edge.
Best,
==Luong

Re: M398 Edge Stability Test
The zwear had a very thin tip (not anymore). In addition to cutting stuff, they use it as an ice pick and prying frozen meats apart. It lives a very rough life.bluntcut wrote: ↑Tue Nov 03, 2020 11:31 pmHi J.

Surprising m398 compared to m390.
Never have been interested in m390, but will be forced into it with the pattadese.
