Fine-Tip Tweezers: One Steel Strip Bent and Spring-Tempered

Tweezers are two springy arms joined at one end: pressed, the tips close; let go, the spring opens them. They go back to predynastic Egypt. Make them from one strip of tool steel bent in half, temper it to a spring, and file the tips to fine needle points that meet exactly. The picture: Roman tweezers, one strip bent at a loop, with a sliding ring.
