Hollow grind on BK-2

while it's true that your 1/4in Bk2 is never gonna push cut like a 1/16in mora, the cutting performance can be bumped up a lot by how you sharpen it. Did you keep the original factory angle (40deg inclusive)? Reprofiling the edge to 30deg would give a significant increase of cutting ability with only a minimal effect on durability.

If you "just use a old wet stone that was my grandfathers" do you know what the grit is? It may simply be a case of you needing to sharpen the knife to a finer grit. That's why I asked what you want the knife to do that it currently won't. You might not need a drastic change to the blade's shape but just a tweak in the maintenance routine.
 
This knife has a nice factory edge, and I feel that for it's thickness, it can bite. I have only had to strop mine so far, maybe you just need a finer grit, like mentioned.
It can take some practice to perform finer and delicate tasks with thick knives. At the same time, I see no reason to not have a smaller (thinner) knife with me as well. Why not? I like knifes, they like going places, cutting stuff, and feeling useful. At least that's what they are telling me.
 
I like a hallow grind on some knifes. For example my Ka-Bar Dozier is a great little slicer and is perfect for opening bags and the tip of my thumb cause I cut it off not to long ago with this knife as I was slicing a bagel in half.

At least it was my left thumb! :thumbup:

Anyways my point is that I don't think it would be good for a BK2 but you could try it anyways.
 
I really don't know the grit it feels fine and smooth on the red/orange side but the other side is smooth to all I know is that I got a old WWII knife crazy sharp with it but it took me around 10-11 hours
 
Sounds like you may need a new sharpening system. You can get a very sharp edge one a knife freehand with a stone but it takes a lot of practice and quite a few stones, in a series of finer grits, to get a knife very sharp. Remember, many people have different definitions of "sharp".

Have you trued the stone? If it's your Grandfather's it is likely to need some maintenance itself.
