Here’s a unique take on the lowly carpenter’s pencil. The Accutrax Pencil Blade is a utility knife blade made from graphite. It’s not designed for taking notes, as the blade won’t take sideways pressure, but it draws crisp, accurate cut lines. You can continue to use it even if it breaks, and it never needs sharpening. A three-pack sells for around $5.
