When it's time to remodel that outdated room, equip yourself with the Carbide Utility Score ($17). This compact knife features a sharp V-shape carbide tip designed to scribe deep and wide cuts with minimal force into fiber-cement siding, concrete backer board, roofing, linoleum, laminates, plastic and glass. The Carbide Utility Score is built with a convenient cross-cut file located along both sides of the hardened steel blade for smoothing rough edges, a notching saw on the tip of the blade and a striking cap at the end of the aluminum handle.
