Putty Knife

A putty knife consists of a thin metal or plastic blade attached to a handle. It is commonly used to fill cracks, holes, dents, and joints in walls, wood, and other surfaces before painting. The flexible blade allows smooth application of fillers and helps create an even surface for sanding and painting. Putty knives are available in various widths to suit different repair and finishing tasks.
