A cabinet is a usually oblong piece of furniture, often attached to a wall and made of wood, used throughout the world for the storage of clothes or other miscellaneous items. ...
Most household doorknobs use a simple mechanism with a screw-style axle (called a spindle) that has at least one flat side, which is passed through the door latch, leaving some length exposed on each side of the door to which the knobs are attached. Knobs are attached on both sides by screwing or sliding them directly onto the spindle, and then securing one or more retaining screws (set screws) through the knob perpendicular to the flat of the spindle. Doorknobs that lose traction can frequently be repaired by replacing or adjusting the set screw, which prevents them from slipping on the spindle.
The location of the doorknob on the door may vary between a few centimeters away from the edge of the door to the exact center of the door, depending on local culture, decorative style or owner preference. The distance from the edge of the door to the center of the doorknob is called the backset.
Doorknobs can be difficult for the young and elderly to operate, especially infants. If a person lacks a firm grip a doorknob must sometimes be operated using two hands. For this reason doors in most commercial and industrial buildings and in many households now use an operating lever, rather than a doorknob, as the lever does not require a firm grip. Levers are also beneficial on doors with narrow stile widths where the reduced backset leaves insufficient space to comfortably turn a doorknob.

Doorknobs can spread many infections. Some materials, e.g. brass, copper and silver, are poisonous to many germs, via the oligodynamic effect. Brass and copper, for example, disinfect themselves of many germs within eight hours. [1] Other materials such as glass, porcelain, stainless steel and aluminum do not have this effect. Self-disinfecting doorknobs are particularly important in hospitals, but useful in any building. Brazen redirects here. ...

Types of doorknobs
- Entrance
- These door knobs are typically used on exterior doors, and include keyed cylinders.
- Privacy
- Typically used on bed and bathrooms and most trailer parks, while they are lockable (unlockable with a generic tool), they do not have keyed cylinders.
- Passage
- Also known as Hall or Closet, these knob sets do not lock and are used in hall or closet doors.

The Game Doorknobs In parts of the UK and Australia this game is played- if one pupil breaks wind, he/she must shout 'Safety' before someone else shouts 'Doorknobs'. If he/she fails to do so, he/she will get free beats until he/she touches a doorknob. Then the beater must stop. If he/she yells safety for no apparent reason, he/she must get two beats on each side by whoever is in the game.
