Which of the following is NOT a characteristic of Pean forceps?

Pean forceps are specifically designed for grasping large tissue masses and have features that make them suitable for that purpose. They are commonly used in surgical procedures where haemostasis is required, which involves controlling bleeding by grasping large blood vessels or tissue. The jaws of Pean forceps are serrated to provide a secure grip on the tissue, preventing slippage during use.

The distinguishing characteristic of Pean forceps is their construction and intended use for larger, more robust tissues rather than delicate structures. This makes them less suitable for tasks requiring precision and gentleness, which is why the statement regarding their design for delicate structures is not true. Therefore, option D is indeed the correct choice as it does not align with the main characteristics and intended use of Pean forceps.
