Bizalsky Claw Clamp

The Biesal Claw Clamp or Cj-biesa is a tool that is used to grasp or hold a piece of material. It has multiple claws and is used in various fields such as working with wood, metal and other materials.

The Bysal Claw is part of a set of two clamps: one for the hand, the other for the leg. A tool is used to clamp the board while sawing. The peculiarity is that they move on any surface, as long as it is convenient. Having secured a hand or foot to them, we move the board or sheets of metal over the surface and plan. And the light weight allows you to hold the clamp in your hands for years,



The Bisal Claw Clamp is a mechanical device used in experiments aimed at studying the processes of deformation and fracture of solid materials under extreme loading conditions. This clamp was invented by Professor K. Biesalski in the 1960s and has since become one of the most famous and widely used tools in the fields of experimental mechanics and materials science.

The design of the Bisal claw clamp consists of two metal rods connected by a screw and shaped like claws. When the rod is compressed, the shape of the claw-shaped springs changes, which prevents direct contact and eliminates local compression or tension of the surface of the materials. This mechanism makes it possible to measure and analyze the stress-tension and deformation of materials under intense loading without direct contact.

The Bizalsky Wedge-shaped clamp is widely used in materials science to study the elastoplastic and brittle deformation of materials (metals, ceramics, glasses, polymers, etc.), mechanical properties and behavior under various regimes of temperature exposure and cyclic loading, as well as to study the interaction of solid surfaces. It is indispensable in the scientific research of strength, corrosion, heat shrinkage and durability of materials, as well as in the analysis of the resistance characteristics of materials for wear resistance and durability.

With the help of Bisal claw clamps, it is possible to reproduce the mechanical, climatic and temperature conditions associated with extreme situations of space flight and nuclear explosions, as well as when testing the reliability and strength characteristics of materials. The device demonstrates versatility and efficiency, a wide range of applicable technologies and methods, and many practical capabilities for solving complex problems in the field of materials and structures applications.

The Bisal claw clamp is the invention of German dentist Constantin R. Bisald, who discovered and patented this tool in 1960. The use of this clamp allows you to carry out a complex procedure for removing or correcting teeth without general anesthesia. This was a real revolution in the field of dentistry, since until that moment the removal of diseased and incorrectly positioned teeth was carried out only with the help of anesthesia.

Why exactly the claw clamp received the greatest recognition among dentists and became
