Developed in 1875 by Arnold Dumont in La Sagne, Switzerland. Dumont produces high quality handmade tweezers, and has gained the popularity of all researchers over the years. There is a variety of material which is used to make Dumont tweezers, as is shown in the link below:

• Biological Grade: Made from Dumoxel steel, the highest quality steel that is available. These tweezers have very fine points, they are non-magnetic, and anti-corrosive. They are the most reliable for all of your precision work.
• High Precision Grade: Made from (Inox) stainless steel, these tweezers have fine points and they can be used as a substitute for Biological Grade when non-magnetic tweezers are not required.
• Epoxy Coated: Made from non-magnetic steel with an epoxy covered handle (tips are not coated); ideal for working in conductive environments.
• Medical Grade: These tweezers are made from stainless steel. They are anti-magnetic and come with a clamping ring, which slides easily into a locking or release position. The tweezers have serrated handles.
• Electronic Grade: These tweezers have a slightly larger tips than the High Precision grade. These tweezers are made from carbon, stainless, and antimagnetic steel.
