Buzz Saw and File
Named for the whirling star and triangular-shaped file segments, the maker of this pattern is unknown although Cambridge, Imperial Glass and U.S. Glass are considered possibilities due to similar patterns made by each.

The water pitchers are 10 and 8 3/4 inches tall. The three tumblers are the ice tea tumbler 5 1/2 inches tall; the standard tumbler 4 1/4 inches tall and the juice tumbler 4 inches tall. Also found is this 6 1/2 inch tall goblet. Another shape is a sherbert as shown below.

Marigold seems to be the only color although green pieces have been reported. Without photos, though, the color green is unconfirmed.
The predominate features of Buzz Saw and File are a large whirling star on two sides of each piece, below which is a smaller hobstar separated be two triangular file designs. The other two sides feature a hobstar separated by triangular files, above which is a hobnail or cane type design. The pitchers and the tumblers have a large buzz saw figure on the underside of the base. The smaller tumblers, goblets and sherbets have a slightly different pattern arrangement but all of the motifs used are the same. The goblet and the sherbet have a whirling star under the base.
