Landscape drawing techniques'' ) (first chapter: "Tools and materials'"), 2004 (ISBN 978-1-58180-584-0).〕 == History == Ever more efficient means of mass production of pencils has driven the replacement cost of a pencil down. Before this, people would continue to use the stub of a pencil to delay the cost a new one.〔Henry Petroski, ''The Pencil: A History of Design and Circumstance'', New York: Random House, 2010 (ISBN 0307772438).〕 For those who "did not feel comfortable using a stub, pencil extenders were sold. These devices function something like a ''porte-crayon''...the pencil stub can be inserted into the end of a shaft...Extenders were especially common among engineers and draftsmen, whose favorite pencils were priced dearly. The use of an extender also has the advantage that the pencil does not appreciably change its heft as it wears down." Artists currently use extenders to maximize the use of their colored pencils. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pencil extender」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
