Abstract
A double-edged utility knife for carpet installers, roofers, glaziers and sheet rock workers has a two-part handle. The handle clamps a detachable reversible double-edged blade at a transverse angulated position with respect thereto. Vertical cuts can be made in tight corners without applying excessive force. The transversely angulated knife blade affords access permitting vertical cuts in tight corners. During cutting the user's hands are displaced from the cutting line, and kept from being inline with the cutting blades. Operation-induced injuries are virtually eliminated. The double edge blade is provided with a geometry especially well suited for wallboard, roofing, carpet cutting/glue scraping and glazier use.
