Each Woodpeckers T-Square consist of a precisely machined, laser engraved, aluminum blade perfectly fitted to a solid, billet handle with support steps to prevent tipping. Both critical parts are fastened together with screws offset to create tensions between the blade and handle for mechanical soundness. The blade itself has precisely spaced 1mm holes machined every 1/16-inch and will fit both standard and mechanical pencils. Blade edges are formed at a 30 degree bevel and engraved with precise inch scale markings graduated to 1/32-inch. The beveled design reduces parallax and increases measuring and marking accuracy.
