Crain 985 Quarter Moon Knife with/Pouch is used for trimming excess welding rods from the seam area after cooling to make the seam area flush with the rest of the floor. It is used in a two-step process in conjunction with the No. 986 Trim Guide. First, insert the trim guide beneath the knife and trim off the bulk of the material on a first pass. Afterward, remove the trim guide and make a second pass with the knife only. The fine cut of the second pass finishes flushes with the surrounding floor. The knife comes with a protective pouch. The blade is resharpenable. The trim guide not included.
