Because of the lack of published trowel and masonry tool histories, the information here is based on other sources that may be less reliable and certainly are incomplete. These include eBay and tools that I purchase myself that are the starting points for my research. I will write what I know as I learn it.

Line or Corner Blocks

W. Rose patent line block
Line blocks, also called corner blocks, have been made in a variety of shapes and materials including wood, aluminum, steel, iron, and plastic. The cast aluminum line block below was made by United Builders of Muskegon, Michigan. W. Rose made cast iron corner blocks, on page 24 of their 1929 catalog. The Rose tools were invented by Daniel Lee (1880-1944), an Irish-born bricklayer in nearby Chester, PA, who received US Patent 1066926 on 8 July, 1913.
