- In the context of art and culture, the culture of the indigenous peoples of the northern polar region of the earth, including the Arctic Ocean and the northernmost parts of Asia, Europe, and North America. The term may also refer to the animals, plants, climate, geology, geography, and oceanography of the area.
- The rigid, calcareous material that is white in color and forms the skeleton of vertebrates; primarily composed of calcium hydroxyapatite with smaller amounts of calcium carbonate, calcium fluoride, magnesium phosphate, and ossein, a high molecular weight protein. Bones have a concentric structure with central lymphatic canals surrounded by a spongy lamellar region protected by a dense outer cortex. Bone has been carved and used since ancient times for many purposes, including fish-hooks, spear heads, needles, handles, and art objects. Bones were also burnt to produce bone black and boiled to produce bone glue. Bone can be distinguished from ivory by being generally whiter, more porous, and less dense.
- Cutting instruments consisting of a blade with a sharpened longitudinal edge fixed in a handle, either rigidly as in a table-, carving, or sheath-knife, or with a joint as in a pocket- or clasp-knife. Knives may be used to cut food, especially in serving and eating, as weapons, and for other purposes. The blade may be of steel or another metal or stone, as in the flint knives of early man, or of another material such as ivory or wood (as with a paperknife). The term also refers to tools that are shaped or used as knives, even if the edge is not particularly sharp or actually used for cutting.
- Objects, especially those hand-held, for performing or facilitating mechanical operations.
