The bottom of the lower plate has stops parallel to the hinge. The stops engage the edge of already laid floor covering and the to-be-laid material is positioned between the plates. The free edge of the upper plate now serves as the cutting guide. It is slightly closer to the hinge than the stop means to ensure a slight overlap of the materials to require a tight or force fit at the joint.Field of SearchBlade or material guide | |
