The 5 Best ruling pen Compass (2023 reviews)

The staedtler ruling pen compass's material feels more premium than its price would suggest. This compass just squeezes the pen or pencil with a curved plastic piece—nice design. It can precisely draw any circle or arc at a wide range of diameters. The metal and plastic pieces are held together with tiny little roll pins that flex. It allows for pen-like objects quite a bit wider than a standard pencil, so even fancy gel pens can fit into it and be tightened in.

The attachment affixes securely and accommodates both fine-tip and standard-tip sharpies, as well as your personal favorite mechanical pencil or pen. Additional leads are easy to come by, and it has an attachment that allows you to use any standard pencil for markings. It is easy to use and sturdy. The squeeze-release adjustments are quite nice.

Why We Like This:

Works well as compass and for marking metal
Excellent compass, very smooth and precise
Works with pens and pencils well
