The force required to cut coal with blunt wedges ...

A theory already given of the force required to cut coal with sharp wedges is developed further so as to take account of blunting of the wedge. It is assumed as before that the coal breaks by tensile failure along a circular arc originating from the edge of the wedge. The effect of blunting is to impose a compressive stress on the coal which ...

Force Required to Crack a Walnut [Archive] - Straight Dope ...

It's the force-per-area or pressure (e.g., PSI) that gets things done. If you can apply the force in a small enough area at a weak enough point, you don't really need all that much. Say, if you try to stab me with an unsharpened pencil versus a sharpened pencil. The same force is going to have a very different effect based on the initial pressure.
