Question on the new 3v HT protocol and blade geometry

I had the opportunity to hold and use Nathan Carothers Chopper today and i was surprised on how thin the edge geometry and how much hacking and batoning it took without any damage. My question is, are the future models going to have the same thin geometry and is that something that can be done in a large production scale? I'm aware than the current models already have thin geometries but Nathan's are much thinner. I truly believe that the best way to take advantage of the this HT is to go thin, thin, thin.....
 
I would be almost certain that Guy wouldn't deviate from his design right now. Not in the middle of all the builds with no r&d on the subject. He's too ocd for that.
 
I had thought that the most of the later larger models would be coming in D3V. Guy & Nathan have been collaborating on the new heat treat.
 
The current LC is .188, the GSO 10 is going to be .200. This is pretty close. The grind, and the edge geometry are not something I have seen detailed on the GSO 10 yet. But as Guy is designing his knife as a do it all knife, and Nathan has his as a dedicated chopper with a fuller, I would guess Guy would be making his grind and edge with the new HT in mind, but still a little heavier than Nathan's LC as he always wants to lean towards the super strong design.
 
I don't know if this answers the geometry question, but I know I read quite awhile back that Guy was thinning the edges on the new spec designs compared to the old.

As far as the heat treat, everything including and after the 4.1 should have the delta.
 
I like the slightly more robust idea too. Gso 12 for president/purge companion. Also I just think that with the new heat treat the thicknesses we have already will be that much better. Because guys knives already have thin geometry.

Old gso 10 is .188. I live really close to Nate. If I win a chopper ever I'm gonna ride up to pick it up. Inside of an hour drive. Gonna take gso 10 and 7/7 with me to compare.
 
I agree with Ol'Tex.

My thought is that the 4.5 is going to be testing ground for pushing the limits of HT and geometry

I dunno if I need to see more to believe in it. Between cutting nails, concrete and being bent past 45 degrees and returning to straight, I'm convinced.
 
From what I've seen and heard, the new delta heat treat on CPM 3v and INFI steel are really respected for all the performance aspects that are desire able in a blade.

Are these two steels really the best available? Is there anything I've missed that can compare?

Honestly, I got into SURVIVE! because I liked the designs on an aesthetic level and I couldn't find a bad review of their performance. Objectively speaking, did I stumble across the best performing steel in the industry?
 
I think the D3V has been optimized for it's purpose which includes harder use and bush chores. I think once again it is a question of intended use. There's better kitchen knife steel and others that would hold a better edge but generally won't be as tough. And definitely other tougher steels, but might not hold and edge as well. Or other steels might be a lot more expensive. I think the D3V is a great combination of edge retention and toughness. In a small knife I'm not going to knock around (like my coming 3.5) i'll get something that will just hold an edge better, like the 20CV.

It seems for now these two are at the apex of steels that hit all the notes for a hard use fixed blade. Nice balance of edge retention/corrosion resistance/lateral strength/toughness

Edge geometry on the NTM Light Chopper has been measured at 0.032" 20-dps.

Edge Geometry on the First Production Run GSO-10 was 0.050" 25-dps but I have no idea if that changed for the 2nd Production Run. My 2016 GSO-5.1 edge geometry is 0.021" 20-dps, making it the thinnest-edged knife of that size that i own (apart from one fillet knife that is also much thinner in general and most definitely not designed for the same type of use :p )

I would love to know what geometry the second GSO-10 run had and what can be expected from the upcoming 3rd generation...
