A ring opening plier is a specialized tool used in body piercing studios and jewelry making to open and close captive bead rings (CBRs) and other types of jewelry rings. Here are the key features and details about ring opening pliers:

1. **Purpose:** Ring opening pliers are specifically designed to safely and effectively open and close jewelry rings without damaging the metal or the jewelry piece itself.

2. **Design:** These pliers have a unique design with small, grooved jaws that allow them to grip the ring securely. The jaws are typically curved to fit the shape of the ring, providing a controlled grip for manipulation.

3. **Material:** Ring opening pliers are commonly made from stainless steel or surgical steel, known for their durability, corrosion resistance, and suitability for sterilization. This ensures they can withstand repeated use in professional settings while maintaining hygiene standards.

4. **Usage:** Piercers and jewelers use ring opening pliers by positioning the ring between the jaws and gently squeezing the handles. This action opens the ring, allowing for the insertion or removal of beads, charms, or other jewelry components.

5. **Versatility:** They are versatile tools used with various types of rings, including captive bead rings (CBRs), segment rings, and other types of body jewelry rings. They are also used in jewelry repair and modification.

6. **Professional Use:** Ring opening pliers are essential tools in piercing studios and jewelry workshops, where they facilitate the installation and removal of jewelry with precision and minimal risk of damage to the jewelry or the wearer.

7. **Hygiene:** Like other piercing tools, ring opening pliers undergo sterilization procedures, such as autoclaving, before each use to ensure they are free from contaminants and safe for use on fresh piercings.

In summary, ring opening pliers are indispensable tools for piercers and jewelers, providing precise control and safety when manipulating jewelry rings. They contribute to a professional and hygienic environment, ensuring the comfort and safety of clients during piercing procedures.
