I’m glad they can produce the different grinds and offer them at reasonable prices. I have learned how to use the hollow grind and have come to like it better than flat. So I guess it is a personal preference more than a absolute state. As for cutting veggies I have a fine set of kitchen cuttlery and for bushcraft I use my 110 Alaskan guide s30v hollow grind or Vantage Pro with no problems.
Indeed! Personal uses differ and so do personal preferences.
For pure bushcraft stuff (wood gathering, tinder making, making shavings, general wood working), I definitely prefer more thickness behind the edge as my hand can more reliably make shavings easier. I also find that a convexed saber grind splits would with more power, less friction and less damage to the edge than a comparable hollow grind. We have a Buck Reaper and use it side by side with both full flat knives and convex saber knives. So we get to see the differences. The issue with the Reaper is the sharp shoulder on the transition between the hollow grind and the flat run to the spine. It really concentrates friction in the wood, whereas the convex saber grinds split more more an axe/hatchet. IME, this is very similar to how an Estwing hatchet with its high hollow grind is very good for limbing but really lousy for splitting kindling compared to a traditional convex hatchet.
For camping use, I prefer more versatility than a pure bushcraft knife. We don't like to carry too much stuff, even when car camping. So I want one knife that is able to handle both food prep and kindling prep. I find modern hollow grinds and fat saber grinds both hang up in things like potatoes. I've never developed a good feel for making shavings with a hollow grind. I'm sure that's just my own shortcoming but it's not from a lack of trying. I find a full flat grind to be more versatile. And I find a thin convexed saber grind like that old Schrade even more versatile. Regardless, for camp knife use, I see these new FFG Bucks as a huge step in the right direction. Which is to say, I pretty much agree with Ron Hood's approach to multi-purpose knives in terms of grinds.
For EDC use, I carry a 110 pretty much most days. I've got 2 in current rotation. I've got a standard brass 110 several years old and a newer aluminum framed one from C&C (my favorite frame, by far). On the older standard, I've scrubbed down the shoulder of the blade so the top half is more like a FFG. The newer 110 is still as it came to me, with a very distinct transition line. The flattened 110 does everything better than the stock blade. The difference when cutting potatoes or cardboard is dramatic. The blade moves through the stuff being cut with much less hang up.
I can understand why Buck doesn't do this though. Scrubbing the shoulder down flat makes the blade less visually interesting. It looses the aesthetic of a sharp clear grind line that adds to the 110's visual appeal. And I accept that visual appeal sells more knives than performance does. So I just live with the need to scrub my Buck's down to flatten out the shoulders. Works better for me that way.
