Pronunciation: [ˈɪŋk nˈa͡ɪf] (IPA) 
Ink knife is a tool used for scraping dried ink from printing press rollers. Its spelling is influenced by the pronunciation of the words 'ink' and 'knife'. The 'i' in 'ink' is pronounced as /ɪ/ and the 'k' in 'knife' is pronounced as /nʌɪf/. Combining the two yields 'in-knife' with the final /n/ being dropped in casual speech. Consequently, the word is spelt as 'ink knife' with no 'n'. Its phonetic transcription is /ɪŋk naɪf/.
An ink knife is a specialized tool used in printmaking, bookbinding, and other artistic applications for handling ink or glue. It typically consists of a thin, flat, and flexible metal blade with a pointed tip and a wooden or plastic handle. The blade is usually around 6 to 8 inches long and can vary in width. The purpose of an ink knife is to manipulate and distribute ink or adhesive materials with precision.
In printmaking, an ink knife is used to transfer ink from a container (such as an inkwell or tube) onto a printing plate, such as a linoleum or woodblock. The sharp tip allows for accurate and controlled application of ink, ensuring the desired areas are evenly covered. The blade can also be used to mix different inks or to scrape away excess ink from the plate, allowing for fine adjustments and corrections.
Bookbinders often employ ink knives to spread glue onto various surfaces, such as book spines, covers, or endpapers. The thin and flexible blade allows for the smooth and consistent application of adhesive, ensuring proper adhesion and avoiding excessive mess. Ink knives are also useful for removing excess glue or cleaning up any stray adhesive from the work.
Overall, an ink knife serves as an indispensable tool for artists, printmakers, and bookbinders, providing them with the precise control necessary for working with ink or glue.
The word "ink knife" combines two separate terms - "ink" and "knife" - to refer to a specific type of tool used in printing and bookmaking.
- "Ink" originates from the Old English word "inca", which means "dark fluid" or "black fluid". It can be traced back to the Proto-Germanic word "inkwiz" and the Proto-Indo-European root "enka".
- "Knife" comes from the Old English word "cnif", which is akin to the Old Norse word "knifr". Both these words have common Proto-Germanic origins.
Combining the words, "ink knife" essentially refers to a knife-like tool used for handling ink, specifically in tasks like spreading, mixing, or cleaning ink during printing processes.
