Rule Magnifier

In addition to accurate marking, it is ideal for fly-tying, sliver removal, blade edge inspection, etc.
The jointed stainless-steel post has a magnetic friction hinge that holds the magnifier at any angle of orientation.
The internal O-ring in the base stabilizes vertical and rotational shaft movement.
The freestanding base also has two rare-earth magnets in it to secure it to a steel rule.
The 3X magnifier has a 1-5/8' field of view.
