I don't hunt so I have no clue, but is there any reason you want a really heavy hunting knife, especially the folding variety? I was looking at some Buck folding hunters that's on sale, and it seems to me they are intentionally adding weight to it. There's the liner lock, then two extremely thick slabs of stainless handle, then two more even thicker rubber handle on top of it. To top it off there's a thick stainless backspacer. In the end you have 8 oz of steel for a 3.5" folder, with a lot of weight that's essentially non-functional (SS handle and spacer). That's almost the weight of some large fixed blade!
So any hunters have any insight?
