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.

Famous quotes containing the word maintenance:
“In public buildings set aside for the care and maintenance of the goods of the middle ages, a staff of civil service art attendants praise all the dead, irrelevant scribblings and scrawlings that, at best, have only historical interest for idiots and layabouts.”
—George Grosz (1893–1959)
“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)
“... in the fierce competition of modern society the only class left in the country possessing leisure is that of women supported in easy circumstances by husband or father, and it is to this class we must look for the maintenance of cultivated and refined tastes, for that value and pursuit of knowledge and of art for their own sakes which can alone save society from degenerating into a huge machine for making money, and gratifying the love of sensual luxury.”
—Mrs. H. O. Ward (1824–1899)
