Dip the fountain pen nib into the bottled ink, making sure it is slightly above the gripping portion. To pull ink into the converter, twist or move the plunger in the other direction.

For example, "he's a good waterman" or "she's a tough woman to work for." The phrase comes from fishing, where a "waterman" is a person who manages the bait shop or dock office while a fisherman goes out on the water. The waterman keeps an eye on things while the fisherman gets his bite. In modern usage, the term refers to someone who works with ink and paper -- especially someone who works in a printing office. Waterman used to be a brand name of ink cartridges, but they are now made by other companies.
