Handles come in wood, plastic (with dual-color handles that are both visually appealing and comfortable to the touch), and metal, as well as all-plastic putty knives—chosen based on the user’s preferences and intended use.
Common surface treatments for blades are divided into standard polishing (where steel strips undergo sandblasting right after leaving the factory) and mirror polishing (a type of metal strip surface treatment that achieves a mirror-like finish).
A putty knife typically consists of a blade and a handle, with blade materials primarily including carbon steel (45#, 50#), 65MN, and stainless steel.
In everyday life, a very small number of people also use it for other purposes—such as iron griddle vendors employing it to flip food.
Easy to use and convenient, it can be scraped, scraped off, applied, and filled—making it widely used in both construction projects and everyday life.
The putty knife is categorized as a painting accessory tool and is a hand tool frequently used by painters.
