Specially made for sheet goods flooring work, Gundlach craftsmanship is applied to make these tools straight and parallel. Prove this to yourself by putting two of them together. They are 2-1/2" wide x 1/8" thick and just heavy enough to hug the floor nicely. The hard steel resists knife blade wear, and it is heat treated to prevent the loss of accuracy from dropping or other abuse. Finished in a pleasing eye strain saving green. Nail holes are provided on one end, and the opposite end of the straight edge is cut on an accurate 45? angle for miter work. Dimensions listed are actual overall lengths.
