The gold-handled needle holder, which features tungsten carbide inserts, is designed to withstand more aggressive cleaning methods compared to other instruments. Tungsten carbide is a very hard and durable material, allowing for the use of metal bristle brushes without the risk of damaging the instrument. These brushes can effectively remove debris and contaminants from the robust surface of the tungsten carbide inserts.

In contrast, the black-handled needle holder and stainless steel needle holder are more vulnerable to scratches and damage from metal bristles. Using a metal brush on these types of needle holders may lead to compromised performance, diminished lifespan, or potential contamination issues due to surface damage. Thus, the gold-handled needle holder stands out as the only instrument suitable for cleaning with a metal bristle brush due to the specific properties of tungsten carbide that enable it to handle this method safely.
