Volume 21 is Blackwing’s tribute to the craft of woodworking, crafted with special finger-jointed slats and featuring their first-ever square barrel. The pencil’s firm graphite is perfect for measuring and marking cut lines—then measuring them again. An art form perfected by the American Shakers, woodworking is an exercise in precision, intuition, and mindfulness. The adage “measure twice, cut once” encourages woodworkers to slow down, be present, and make purposeful choices. A good rule for woodworking, and a good rule for life. Set of 12.
