Problem with prybars, they are heavy. And they are designed (curved) in a way they are hard to EDC. I wish to have a heavy (not necessarily large, but heavy) knife similar to the japanese soil knife, straight and relatively sharp/dull.

I once bought a cheap 'bushcraft knife' , not for real bushcrafting, but for this reason. It is cheap (meaning: not a very good steal) but it was thick. I wanted it for all around digging, gardening , whatever. Unfortunately since we moved the furniture and stuff around the house, I haven't seen it and don't know where it is.
