Shaft length

The shaft length varies up to one meter, is predominantly 8 to 12 cm. Only the top mouth opens alligator-like. (in US therefore has the medical term "Alligator Mouth" or "Hartmann Alligator Forceps" enforced. A common name also is "Crocodile forceps"[2]). The standard length of the muzzle from the front hinge implementation is 1.5 cm or 1 cm. Thus, the clamp is used where normal tweezers or fine instruments are struggling to grasp small objects. So you can even grasp objects in small tubes and position them precisely.

Clamp

The ear clamp is used wherever problems exist with normal tweezers or fine instruments to grasp small objects. It opens only a small part of the mouth. So you can even grasp objects in small tubes and position them precisely. Ideal during soldering, when it is difficult to accurately position small components. In veterinary medicine the Hartmann, ear polypus forceps is used to remove awns or epilate hairs of dogs ears. The design reduces the natural tremor (shaking).[3]
