A bottom face processing method of a pillar-shaped honeycomb structure including steps of: preparing a pillar-shaped honeycomb structure including a plurality of first cells which extend in parallel with each other from a first bottom face to a second bottom face, and each of which is opened in the first bottom face and has a protruding plugged portion in the second bottom face, and a plurality of second cells each of which is adjacent to at least one of the first cells with a partition wall interposed therebetween, which extend in parallel with each other from the first bottom face to the second bottom face, and each of which has a protruding plugged portion in the first bottom face, and is opened in the second bottom face; and removing the protruding portion from the plugged portion of each of the first cells and the second cells of the pillar-shaped honeycomb structure.

A method comprising: a) contacting an article comprising one or more blades (10), the one or more blades (10) having a leading edge (12) curved upward and separated into prongs (14) by one or more notches (16) in the one or more blades (10), with two or more substrates (20,22) joined by a pasty material overflowing at one or more seams (18), where the one or more notches (16) of the article straddle the one or more seams (18); and b) moving the article or the substrates (20,22) such that the pasty material overflowing at the one or more seams (18) is removed.
