Abstract
A wooden flooring strip having a top surface having a decorative finish and a base surface opposed to said top surface. The base surface has a multiplicity of closely spaced-apart scores extending into the flooring strip from the base surface transverse to the length of the flooring strip along substantially the entire length of the flooring strip to relieve stress and increase flexibility in the wood strip for more closely adhering to irregularities of a sub-floor. The flooring strip has substantially longitudinally-extending wood fibers in an area of the flooring strip between the scores and the top surface of the flooring strip which have been broken to an extent sufficient to relieve tension on the top surface of the flooring strip and to equalize tension on the wood fibers adjacent both the top surface and base surface of the flooring strip.
