Maintenance
Maintenance of the saw blade will depend on the type and or age of the tool. Older key hole saws with filed crosscut teeth will require the craftsman to manually set and sharpen the teeth by hand. For contemporary versions of the retractable blade variety replacement blades are readily available thus removing the skills, tools and time that would otherwise be required to manually sharpen the blade. Mass production of cheap throw away versions of the fixed blade type make it cost effective for the tradesman to do exactly that and purchase a new replacement when the teeth become blunt.

“My course is a firm assertion and maintenance of the rights of the colored people of the South according to the Thirteenth, Fourteenth, and Fifteenth Amendments, coupled with a readiness to recognize all Southern people, without regard to past political conduct, who will now go with me heartily and in good faith in support of these principles.”

“However patriarchal the world, at home the child knows that his mother is the source of all power. The hand that rocks the cradle rules his world. . . . The son never forgets that he owes his life to his mother, not just the creation of it but the maintenance of it, and that he owes her a debt he cannot conceivably repay, but which she may call in at any time.”
—Frank Pittman (20th century)
