Dumont Pattern No. 1 Tweezers are Swiss-made precision instruments designed for general use, assembly, and inspection work. Featuring tapered shanks with beveled edges and sharp, plain-finished points, these tweezers deliver the controlled handling demanded by professional jewelers, watchmakers, and metalsmiths. Overall length is 120mm (4-3/4") with tips measuring 0.15mm wide by 0.20mm thick.

Available in two quality grades — High Precision (HP) and Electronic Quality (EQ) — and across multiple metal alloys, these tweezers can be matched precisely to the demands of your work environment.

The High Precision (HP) grade features extensive hand finishing and represents Dumont's finest quality. These are the tweezers relied upon by the world's most exacting watchmakers. The Electronic Quality (EQ) grade offers less hand finishing than HP and is engineered for assembly work, making it an excellent choice for dependable everyday use.

  • Tapered shanks with beveled edges for controlled grip and handling
  • Sharp, plain-finished points for fine assembly and inspection tasks
