wow...
it's not just edges and spines that have to do with everything.
you can have a thick blade outcut a thinner one because it's geometry is better.
It just depends.
look at the bravo1 for example, it's pretty thick but it would probably outcut alot of knives of even thinner stock.

I really don't get what that guy was talking about at all.
I see where he is coing from.. just don't see what he's trying to get at.
don't know where we went from thin stock tot hick... maybe some made knives of thick stock when they found out they could grind them to cut good AND be able to pry, split wood and stand up to tougher use.
I guess some companies started making them thick too, but maybe they didn't cut that well.

thick prybar knives have their place though, as do thin knives.
alot of people use them in urban environments so thick prybar type is good for them.
