A floor groover used to facilitate specialized heat welding of floor covering materials. The groover cuts a groove for receiving a welding rod at the edges or seam of abutting pieces of flooring materials. The groover can provide for a groove not only up to the wall, but also up the wall and in the radius of the coved-sticked area. Some embodiments of the groover can provide enhanced freedom of movement, which can be helpful when creating grooves of certain shapes in the flooring.
