The duck bill trowel, also called a coke trowel or duckbill trowel, has a narrow taper with a round tip. A typical size is 10" x 2". Today, the duck bill trowel is used for finishing tight inside corners and curves, such as curb and gutter faces and other awkward spaces.
Coke trowels include the duck bill trowel and other shapes as shown in the 1939 Marshalltown catalog. The name originated from their use to seal coke ovens, according to Disston's 1932 catalog. Marshalltown makes 2 styles of coke trowels today, like the second and fourth from the top in the picture below.
