drywall knife or trowel

Most of the tools in this set are made from carbon steel, stainless steel, or aluminum alloy, according to the product details.

Trowels use both V-shaped and square (U- or square-notched) profiles. Common notch sizes shown include depths/widths such as 3/16 in and 1/4 in, with example notch spacing like 1/4 in.

Finishing trowels commonly list blade lengths around 11 inches; wide finishing blades are shown at about 10.9 x 4.4 inches (roughly 4.4–4.5 in wide). Larger skimming knives for broad smoothing can be listed up to 32 inches long.

Several stainless-steel finishing trowels list a 0.6 mm blade thickness, while a large skimming blade listing specifies 0.5 mm stainless steel.

A skimming blade listing explicitly describes an interchangeable blade design that allows users to swap out worn or damaged blades; the listing also notes that replacement blades are not included.

Finishing blades meant for even application commonly have a wider profile, for example about 10.9 x 4.4 inches (roughly 4.4 in wide), to increase surface contact for more uniform results.
