I'm actually on the fence on this. I'm currently waffling between .275 and .300.
I want to make an authentic Kukri geometry that works like the real thing, not just a kukri shaped object, and the "real thing" is pretty thick. But part of the reason it's so thick is because the materials used and the application dictate it. Our material does not have many of those constraints. Delta 3V is not going to break, our hands are untied and we can achieve geometries that the traditional makers wouldn't dare.
A key design element, that is not intuitively obvious, is the primary grind angle. The OG "original real deal" is quite obtuse and needed to be because of the poor quality historical materials. However, we know from our knife racing, the optimal geometry for chopping wood is in a particular range (that we can reach) and the kukri are typically well over that range. We do not have the design constraints of the original materials and I would not be doing my job if I didn't tweak the angles where Delta 3V really shines in this application. These narrower angles lead to taller grinds which begin to conflict with the geometry, and therefore weight distributions, of the original kukri. My challenge is to tweak the geometries on this historical design a little bit and bring some of the performance characteristics that we have attained to this piece. I think we are looking at a double twisted grind to do this which is going to mean a different kind of manufacturing process than we usually use.
Long story short, I don't know exactly what the final stock thickness will be yet, I'm still working on
