Abstract: A cutting tool such as a saw blade or drill bit, having a cutting portion having a body and one or more cutting tips on the body. A set of markings on the body indicate the distance between the cutting tip and each marking, to indicate to a user the depth of cut to which the tool has penetrated into a workpiece. The markings can be painted, etched, printed, peened on the body or applied in other desired manner.

Abstract: An article of furniture such as a table, having four sides connected to each other by corner hinges. Two of the sides are each formed as two halves hinged together and normally rigidified by top rails, and by a horizontal work support panel located between the sides. When the work support panel is lifted and removed from the front, and the top rails are removed, the hinged sides can be folded inwardly so that the table frame assumes a relatively flat configuration. The front side of the table can be formed as two separate pieces, in which case the intermediate hinges in the sides can be removed. The table can also be made in a three-sided configuration, or in a bookshelf or cabinet configuration.
