Beveled point leather working knives have a beveled edge to the blade. This helps for skiving and edge trimming where you want a little more control over how deep the cut is and how the path of the blade moves through the cut.
For example, you might want to cut fairly deep into the edge and taper it up as you move forward. You might want to taper a cut out as you move along an edge, or even just shave a tine bit of leather from a surface when doing finishing work. The beveled shape of the blade will help with this.
