Knur is a noun that can be defined as a small, rounded, or knobby protuberance or ridge, often found on the surface of a material or object. Typically, a knur is a small bump or indentation that is intentionally incorporated into the design or construction of certain objects for functional or decorative purposes. Knurs can be found on a variety of items, such as tool handles, machine parts, or even furniture, where they may serve to enhance grip, prevent slipping, or simply to add a distinctive texture to the object.
In woodworking or metalworking, knurs may be intentionally created as decorative elements by carving or machining the surface of the material to produce small, raised or recessed areas. These knurs may be arranged in patterns or particular shapes to achieve a desired aesthetic effect. Additionally, in the realm of sports, knurs can be found on certain implements such as sports balls or boards, where they assist in enhancing grip or control.
The term "knur" originated from the Middle English word "knurren," which means "to growl or complain," likely due to the rough or irregular appearance of these protrusions. Overall, knurs serve various functional and aesthetic purposes in different contexts, adding surface texture, grip, or visual interest to the objects on which they are found.

The word "knur" has an interesting history and its etymology can be traced back to Old English.
"Knur" originated from the Old English word "cnotta", which meant "a ball" or "a knot". It later evolved to "knurr" and eventually transformed into "knur" in Middle English.
In Middle English, "knur" had several different meanings. It was used to refer to a small hard ball used in certain games, such as in the game of marbles. It was also used to describe a knot or protuberance on a tree trunk or branch.
Over time, the usage of "knur" expanded to include various other meanings. In some dialects, it was used to describe a small hard lump or bump on the skin. In Scottish dialects, it was associated with a hard round object, such as a hard knot in timber.
