These pliers are specially designed for biots, with the pliers body positioned parallel to the material.

The tip is thin and ideal for wrapping short goose biots.
The rubber parts of the joint have moderate elasticity and can be expected to function as shock absorbers.
The inside of the tip is sandblasted to securely hold enamel biots.

The inside of the pliers is sandblasted to give it a non-slip finish, firmly gripping goose biots, etc.
The edge of the tip is curved all around to prevent the goose biot from being cut by the edge, etc.
The shock absorber and O-ring allow it to stretch just enough to not lose the delicate feeling of your fingertips.
The position of the pliers body is parallel to the material, so you can create a biot body without twisting it.
