Style #7 Dumont Tweezers

Dumont Pattern 7 Style Tweezers, provide a tip very similar to the Style #1, but with curved shanks. The curve allows resting the hand on the bench while working. This style would be selected as a matter of personal preference. Like the tip of the Style #1, the tip of the #7 is not as strong as the Style #2.

Style #7, Dumostar Dumont Tweezers, Swiss Made

Top quality is the DUMOSTAR line. The Dumostar are made of a super-hard (Rockwell minimum 61) alloy that is magnetic-resistant (anti-magnetic), and acid and rust resistant. I find the hardness of these tweezers worth the cost, as with careful use, they will keep their points almost indefinitely.

Style #7, Carbon Steel Dumont Tweezers, Swiss Made

Carbon Steel at Rockwell 60 is the hardest steel used in the original Dumont tweezer line. The hardest of carbon steel makes the tips more durable than stainless steel. The benefits of carbon steel comes with drawbacks as well. Carbon is stiffer than Stainless, however is more likely to break if stressed, easily magnetized and will rust and stain if used around chemicals or just plain water or even high humidity conditions. Watchmakers by taking proper care of cleaning, oiling and storing of carbon steel tweezers have been know to use the same tweezers for decades without replacing them.
