The "Ask Nathan a Question" Thread

The addition of carbon to iron, when manipulated with heat makes it hard and strong <--- that's almost alchemy. And there's no chemical reaction. There's not even any molecules. It's simply carbon atoms physically jammed between iron atoms laid out in a metallic crystalline matrix, made possible because of a FCC->BCC flip caused by heat and carbons ability to flow in that crystal.

I learned something new today. Cheers!

The rest of post #169 was interesting. Thanks.
 
Hey Nathan,
Any possibility in gathering a "rough" time frame for when we could expect the HD field knives being designed? I like the idea of the HD version better but dont want to miss out on a regular FK before they are expired IF we are expecting quite a while before the HD version are released.

Cheers
 
Just want to make sure I didn't miss something along the way, but did you determine to build some HD field knives? I must have missed your announcing it.
 
A few pages back

I remember that post. I think I read revisit differently, probably - and didn't place the proper weighting on it's usage given the context of the entire sentence. It does, as I read it now, point toward production probability, huh?
 
Yeah, I'm going to have some sort of Field Knife in the future. And if people want a thin / heavy duty versions of it, I can accommodate that. Probably some time next year.
 
I'll probably start drawing something up in the next month or two
 
I could go for a thin FK.
Didn't think I could use a field knife in my everyday camping/ hiking times. But a thin FK could easily be my bird and trout knife.
 
i can't wait to see what offerings next year brings. LC, HDC, FK models and the SK all sound really great ! Oh yeah and the EDC :-)
 
Hey Nathan, is there any chance of a Survival Knife sale in time to sneak one in my Christmas stocking?

Unfortunately no. That had been the plan but the schedule has slipped. This is one reason we're hiring, so I can open up more time for development. Instead of developing the SK, I'm developing an optimized heat treat for CPM 4V (and Vanadis 4) for the large batch of EDC we're making now. That has the SK development during Christmas, so perhaps other than a couple prototypes there won't be any ready at that time.

No worries, hope all goes well with the job opening and you guys can really ramp up production :thumbup:

Will the SK have Delta 3V or CPM 4V with your heat treatment?

Only experience I have with 4v is with a Spyderco mule, though I haven't done enough with it to get a strong impression on its performance.

Did I remember reading somewhere that Mr. Keffeler has been using Vanadis 4 or 4e (or they're the same? :D) and it's performed to his expectations?

The SK will be the softer (HRC 60.5) Delta 3V we use on the choppers

Dr. Keffeler uses it on his competition cutter that he uses so effectively in the cutting competitions (replacing CPM M4), which is why I'm interested in it. He sent me some to experiment with and I have a sheet of 4V, which is Crucible's version of it (same chemistry) that we're milling into EDC now.

It will almost certainly work very well on the thinner harder knives. The end goal is to see how it works in a larger racing knife and the big choppers.

Apologies on the Dr./Mr. mix-up, I was not aware. Also didn't know that 4v was Crucible's version of/analogous to Bohler's Vanadis.

I have two small, thin knives in M4, RC unknown on one but either 64 or 65 on the other and have been more than happy with them. Excited to try something that is a step up of sorts. :thumbup:
 
that 4v is some impressive looking stuff. I like moly/vanadium rich steels, and this stuff has a lot of carbon too. Very promising, by the numbers
 
Nathan,

What did you dress up as for Halloween?

I went as a psychopath disguised as a middle aged machinist, complete with beer belly, receding hairline and shop stained clothing that might have been current in the 90's.
