1/8 vs 3/16 Jeff White Bush Knife

[Wyoming762]

Hi. I'm looking to purchase either the Jeff White Bush Knife or the Bush Knife HD. The only difference between the blades is that the former has a 1/8 inch blade while the latter has a 3/16 inch blade. The latter also costs 70 bucks more. I'm having a heard time justifying the extra money, but also don't want to end up being bugged by the possibility that I gave myself a disadvantage by getting the thinner blade.
This knife is going to be a general camping, hiking, and outdoor knife. I keep a hatchet with me while doing all of that, but would like the knife to be able to stand up to batoning should I lose, break, or forget the hatchet.
I am not a knowledgeable knife guy, so forgive the stupid questions, but what exactly will the extra 1.5 millimeters do for me? It doesn't support the edge, does it? I Will not under any circumstances be using this as a pry bar, and even if I did, would the fact that it is a pretty wide blade help strengthen the blade and help negate the consequences of a thinner blade? And how is a thicker blade better for knocking it straight through a piece wood with another piece of wood?
I will be getting the convex grind on it.
Thanks in advance.

For field knives, 3/16" thickness generally goes along with a flat grind or very high hollow/saber grind. 3/16" in what is effectively a variation on a Scandi grind with the main body of the blade being mainly very thick and flat doesn't sound advantageous for any use, aside from just wailing on something.

For this tall blade design, 1/8" leaves a lot of metal for strength without getting in the way for slicing or splitting. It is also going to carry much more nicely than the heavier HD. I can't see what you get from the HD aside from a less effective cutting tool.

Having just received the bush knife from jeff white today my first impression is 1/8 " fits the knife perfectly, I couldn't imagine needing anything thicker not to mention the added weight and bulk. Order the original, save the money, and your gonna be happy you did.
