    Abstract: 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.

  • Patent number: 8434235
    Abstract: A cutting assembly is slidably mounted on a T-Square. The T-Square may include a scale having multiple indicia for measured cutting based on the size of the wallboard sheet being cut. The cutting assembly is mounted on a slider which may be clamped at measured positions along the arm of the T-Square. The cutting assembly includes oppositely disposed knife blades which are slidably mounted in a housing and spring loaded on opposite sides of a pivot mount such that when not in use the cutting assembly is urged to level and rests with the two knife blades retracted. As the housing is rotated so as to lower one end, the corresponding knife blade extends from the housing to engage with and score or cut the surface of the wallboard material. The cutting tool may be rotated in the opposite direction to thereby extend from the housing the other blade of the pair of oppositely disposed knife blades.

  • Patent number: 8429825
    Abstract: A cutting apparatus is provided having a resilient handle, a guide on one end of the handle and a cutter body on the opposite end. The guide includes two spaced members forming an outwardly facing slot with a stop formed therein. The handle is flexed into an assembled position to form a close loop, with the cutter body positioned within the guide slot and in contact with the stop. A cutting edge is movable along with cutter body to an activated position, with the cutting edge extending outwardly of the slot and the guide. The movement of the cutter body is caused by an activation force applied to the closed loop of the resilient handle member.
