I dunno what vodka is made from potatoes

Goose is made from wheat
Absolut is wheat
Tito’s is made from corn
Smirnoff is corn
Stoli from wheat
Ketel one is wheat

Which is why I gained so much weight drinking vodka

Back in my wilder days, I gave up on all those brands in favor of Chopin which is Polish potato vodka. There are other Polish potato ones which are pricier but not as readily available as Chopin.

I assumed you may be from California when I saw the buried knife. Because you done get much rain. Then when I saw your 2nd picture. I was reminded of the tarantula nests that I have seen on Mount Diablo in The Bay Area CA. The tarantula mating season is beginning soon. A hike on Mount Diablo in October is sure to find lots of furry eight legged creatures crawling around the trails.

I also found this in the forest.

Wow. Here is an idea ....

Those were a low temp tweak that preceded Delta. It was pretty good. It was really good. But it would take some damage in that nail chop at 20 DPS that is largely gone now. I had to move my test samples to 18 DPS after Delta. But it was waaay better than using the secondary hardening hump.

After that run of Shivs we ran into an issue with the material condition of the 3V itself. With my background in prequenching D2 I thought that would be the answer (and it was but it wasn't) and the actual issue ended up being an issue that could be resolved with normalizing (I'm abusing that term here) rather than prequenching. Austenitizing from an already martensitic matrix worked, but for the wrong reasons and is fraught with risks that I understand better now. Our material is less spheroidized and there are some additional steps added to the process. But, to answer your question, yes those early tweaks performed (as you can see) but were not always as consistent and were never as good as the finalized protocol.

Another issue could actually have something to do with the compaction of the material itself. Despite what they tell you about the benefits of particle metallurgy (it is not inherently cleaner or finer grained, those are misconceptions), its real purpose is (mostly) to create alloys that simply aren't possible with a conventional melt *. Building steel from particle doesn't inherently improve it and (like damascus) can actually cause issues if not performed perfectly. We still test constantly. For whatever reason, the performance of our work is currently stronger than it was when we first started with it (and this is true of current materials I've given the industry HT to also) and I can only speculate that Crucible has tweaked something in their process and not publicized it.

EDIT:

*the PM process allows the steel to solidify in seconds rather than hours. This solves the problem of carbide forming elements like Vanadium falling from solution waaay before the rest of the melt solidifies. It also makes smaller (and rounder) carbides in conventional alloys rending the steel more ductile at a given hardness. This spoils D2 in a knife.

There’s a lot of places I could have posted this but this thread is usually about beer, diesel trucks and childish behavior. This is why I didn’t participate in the sales yesterday, I was out being childish with some buddies…(burnout video)

Great stuff. As for me, I sold my diesels long ago (go 5.3…), don’t drink as much as I used to, and am a utter manchild to the Nth degree.
