The Lindstrom AC-SA are stainless steel anti-magnetic precision tweezers with a serrated handle and a straight, strong, 4.33". The Lindström SL (service level) tweezers are for use in production, assembly, and field service kits. Swiss quality at a lower cost for applications that do not require the highest precision. Like our other tweezers, this one is made of anti-acid, anti-magnetic stainless steel. It has ESD-safe properties for use in sensitive environments. Matt finish for reduction of glare in intensely lit environments.
