A ring opening and closing plier is a versatile tool used in body piercing studios and jewelry making. Here are the key features and details about ring opening and closing pliers:

1. **Purpose:** Ring opening and closing pliers are designed to both open and close captive bead rings (CBRs), segment rings, and other types of jewelry rings without damaging the metal or the jewelry piece itself.

2. **Design:** These pliers typically have dual functionality with different grooved jaws—one for opening rings and another for closing them. The jaws are often curved to fit the shape of the ring, providing a secure grip and controlled manipulation.

3. **Material:** Ring opening and closing pliers are commonly made from stainless steel or surgical steel. These materials ensure durability, corrosion resistance, and suitability for sterilization, making them ideal for frequent use in professional settings while maintaining hygiene standards.

4. **Usage:** Piercers and jewelers use these pliers by selecting the appropriate jaw for either opening or closing the ring. They position the ring between the jaws and gently squeeze the handles to perform the desired action, whether it's inserting beads, adjusting jewelry components, or securing the ring in place.

5. **Versatility:** They are essential tools for various types of rings used in body jewelry, allowing for precise adjustments and installations during piercing procedures or jewelry modifications.

6. **Professional Use:** Ring opening and closing pliers are indispensable in piercing studios and jewelry workshops. They enable professionals to work with jewelry efficiently and accurately, ensuring client comfort and safety throughout the procedure.

7. **Hygiene:** Like other piercing tools, these pliers undergo strict sterilization procedures, such as autoclaving, before each use to prevent contamination and maintain a sterile environment for piercing procedures.

In summary, ring opening and closing pliers are versatile tools that play a crucial role in the precise handling and adjustment of jewelry rings in body piercing and jewelry making. They contribute to a professional, hygienic, and safe environment for both piercers and clients.
