Links to Order an All-Metal Bow Compass
It is important to have a high-quality compass for making accurate designs and geometric constructions. Make sure the compass you order has metal pins for the metal adjustment wheel (as seen in the pictures which accompany the ordering links seen below). Plastic pins will wear out much more quickly. Specify that your compass must be all metal as seen in the picture and that you will not accept plastic pins.
