tweezers
A forceps is to grab a tool that serves small items. The name is derived from the French pince = pliers over pincer = to pinch, to pinch.
construction
Mostly, tweezers consist of two pieces of metal joined together (other materials such as plastics , ceramics or glass fiber reinforced plastic are also used), which move towards each other by applying slight pressure on both parts. The tip of the tweezers is then closed. In the cosmetics industry, light tweezers made of seamless aluminum are preferred. These tweezers are made from cast, anodized aluminum profiles, which are then cut across and ground at the tips.
history
Metal tweezers are known from numerous grave finds since the younger Bronze Age , before they were made of wood, bone or horn.
They used to be called Kluppzange.
variants
Tweezers are available in a wide variety of designs:
- with pointed ends
- with round ends
- with square ends
- straight forceps
- curved or angled forceps
- Cutting tweezers
- Holding forceps (cross forceps) (e.g. ball- holding forceps )
- anti-magnetic and acid-proof tweezers
- monopolar and bipolar forceps ( HF surgery )
Applications
Tweezers are used, often in connection with ear spoons and razors , for hair and beard care and as universal small tools.
Typical fields of application are:
- in lead type
- dealing with stamps (see philately )
- When handling smaller coins (see numismatics ), unlike philately tweezers, the tips of the numismatic tweezers are encased in plastic to protect the coins
- in electronics
- for hair removal
- in semiconductor technology in the form of wafer tweezers
- in cosmetics
- in medicine ( anatomical forceps and surgical forceps )
- in the household
- in jewelry making
- In the textile industry as a dimple iron
- in science
- in the aquarium hobby when planting z. B. Aquascaping
In addition to the tweezers shown in the picture, there are also other tweezers, for example so-called optical tweezers and vacuum tweezers .
