Note: "A putty knife is a specialized tool used when glazing single glazed windows, to work putty around the edges of each pane of glass. An experienced glazer will apply the putty by hand, and then smooth it with the knife. Modern insulated glazing may use other ways of securing the glass to the window frame.

A spackle knife (called a scraper in British English, also known as a spatula in American English) is also commonly called a "putty knife",[citation needed] and is used for scraping surfaces or spreading material such as plaster in various construction trades. Widths from 11⁄4" to 5" or 6" are commonly available. Wider-bladed knives up to about 12" are used for sheet rocking. Larger blades are made, but generally lack the stability of the smaller blades and do not make a perfectly flat surface." - (en.wikipedia.org 18.11.2021)
