Tweezers for handling miniature and micro-miniature parts and assemblies,tweezers are as essential as the fingers on your hand, There are definite differences in their patterns. Oint finish and the materials used make some patterns more suitable for a particular job than others. The tweezers listed below, are manufactured by Peer-Vigor  (made in Switzerland for Grobet USA) and Grobet USA (great value - made for Grobet in the USA).
The Chart below shows general property relationships among the various metals used in manufacturing tweezers. In addition, note that the points of the harder metals will wera longer and are less subject to bending. The Softer metals will not scratch delicate parts and usally have desirable properties such as being non-magnetic etc.
