Available Options

Part # Metal Type Description
157.273 Carbon Steel Strongest metal option; holds an edge longer than stainless steel. Magnetic; requires oiled storage to prevent rust.
157.275 Anti-Magnetic Stainless Steel (Dumoxel) Non-magnetic, corrosion- and acid-resistant stainless alloy. Ideal for industrial and sensitive assembly environments.

Notes

Carbon Steel Care: Carbon steel tweezers will rust if not properly maintained. Store with a light coating of oil or under a lightly oiled protective cloth. With proper care, carbon steel holds an edge and stays sharper longer than stainless steel.

Dumoxel (Anti-Magnetic Stainless Steel): This proprietary Dumont alloy is specifically engineered for use in applications requiring non-magnetic, corrosion-resistant, and acid-resistant properties.
