A cutter for use at the wrapping counter in a drug or confectionery store may be easily made from a double-edged razor blade and a piece of thin board - a piece of cigar box will do. Cut the wood in the shape shown, with a protecting piece over the edge of the razor. Screws are turned through the holes in the blade and into a support on the paper holder or any other convenient place. - Contributed by T. F. Man-aghan, Philadelphia, Pa.
