Like many have already mentioned, the flat primary grind with a convex secondary is an incredibly versatile design. Personally, when I lay all the pros and cons down regarding all the different grinds, this one ends up coming out on top for me. BUT....., there is always a but
For some reason, I am just still always drawn to the scandi grind. Perhaps it is just the stuff that I am doing, but if you ever see me in the woods, 9 times out of 10, I will have a scandi on my belt.
One of my most recent favorites addresses some of the issues noted by KGD. The drawback of the scandi grind is that it reaches full thickness of the stock in very short distance. So, for food prep and such, where you are pushing against a non-deformable material, it does not have much slicing ability.
My solution to that is to go thin with a scandi:
This particular one is 3/32". With this size knife, I am not digging, prying, and doing any Rambo stuff, so the lateral stiffness is not really need for me. Go to a bigger knife, and yes I will switch the grind.
But this particular one is long enough to baton through wood to make kindling like any knife its size. The scandi acts as you would expect on chewing wood. The thinness makes the slicing ability great. The bevel is still wide enough to lock it on to a stone, and yet it is small enough that it doesn't take forever to evenly hone.
These days I cringe a bit when I think of a scandi on an 1/8", but can live with. I don't even want to think about having one on a thicker knife (such as 5/32") but many people order and want one that way.
Just my experience.
