Troweling can be done by machine or by hand. If done by hand, the finisher will float and trowel and area before moving his knee-boards. A fresno is a steel trowel attached to a bull-float handle. Putting a long handle on the trowel allows finishers to trowel the concrete without walking out onto the slab.
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.
Purpose: Fresno trowels are designed to attach to long extension handles so finishers don't have to walk out on the slab. They permit rapid work over large areas, such as driveways, but do not achieve the same degree of compaction possible with hand trowels. However, that can be an advantage when you must trowel slabs early for decorative work because you can create a smooth finish without premature sealing of the surface.
