Need a combination tweezers/magnifying lens? This one wins hands down! Elegantly simple. Easy to use. The short but wide grips on the stainless steel tweezers offer better control, but still come to a fine point. The 7/8" dia acrylic lens is only 3.5X, as opposed to the 6X claimed, but 3.5 works for most jewelers, hobbyists, scientists, and mothers of sliver-impaled children. Sweet.
