A method for manufacturing floorboards, said floorboards comprising wood fibers oriented essentially in a plane, the method comprising:
- cutting a first portion of a single solid unitary piece of floorboard material that is continuous without division to form a first cut in at one portion of the floorboard material, the first cut cutting only part way through the floorboard material;
- cutting a second portion of the single solid unitary piece of floorboard material to form a second cut at a second portion of the floorboard material, the second cut cutting only part way through the floorboard material;
- and
- fracturing the single solid unitary piece of floorboard material along a region connecting the first and second cuts into at least two pieces by providing a force on one of the at least two pieces and an opposing force on the other of the at least two pieces such that the fracture occurs by breaking off a piece in the plane of the wood fibers.
