These reverse action soft replaceable tip tweezers have carbon fiber points. Carbofib™ is a polymer based material with 30% carbon fibers added (conductive 10² ohms/sq). Carbofib™ has very high rigidity, excellent tensile and flexural strength, fatigue and creep resistance, and is temperature resistant to 249°F. The bodies are made of anti-magnetic Neverust® stainless steel (AISI 316L). Because these tweezers are closed at rest, they are ideal for holding items for an extended period of time. They are excellent for handling delicate items.
