A marking knife comes with a single- or double-bevel blade, due to which you can cut in a variety of directions. On the contrary, the blade of a precision knife has only side beveled. This means you need to turn the piece or move around the piece to each area. Still, it is best for marking against a straight edge or slim joints. It is not ideal for the outline of joints with profound areas. On the other hand, a marking knife is more apt for any kind of wood marking. It is relatively tougher and longer.
