Putty knives, essential in various construction tasks, are known for their versatility in scraping surfaces and spreading materials like plaster. These tools, also referred to as scrapers, spatulas, or spackle knives, come with different blade configurations—ranging from stiff to flexible and made from materials such as plastic, carbon steel, stainless steel, or brass. The blade's edge and width significantly contribute to the tool's specific application. While working with compounds, straight, flexible blades made of plastic or steel are preferred, with the latter offering durability despite a higher cost. For scraping tasks, a stiff, chiseled-edge steel or brass blade is ideal, requiring an angled approach to efficiently remove residue.

Expanding beyond traditional putty knives, taping knives serve a unique role in construction, especially in tasks involving drywall. These wider knives, spanning 9 to 14 inches, are crucial for applying drywall compound over extensive areas, ensuring seamless tape feathering on joints. Their utility extends to mud application and embedding tape, with some even featuring a multi-functional hammer-end handle. Additionally, knockdown knives, a specialized variant, are instrumental in applying knockdown drywall texture, highlighting the diverse applications of this tool category in construction and renovation projects.
