The Scalpel Handle No. 4 (Plastic, 13.5 cm) is a lightweight, ergonomic alternative to traditional stainless steel handles, used widely in veterinary medicine, biology labs, podiatry, and educational dissections. Measuring exactly 13.5 cm (approximately 5.3 inches), these handles are designed with the larger No. 4 fitment slot to accommodate heavy-duty surgical blades while providing a thicker, high-traction grip profile that minimizes hand fatigue.
