The Blackwing 21 is Blackwing’s tribute to the craft of woodworking. Each pencil is made with special finger jointed slats and features their first-ever square barrel with a wide face, allowing you to see the finger joints on each pencil. The number 21 represents the wisdom of "measure twice, cut once." The pencil’s firm graphite is perfect for measuring and marking cut lines, and then measuring them again.

Pencils sold in sets of one dozen.
