The durable razor knife has gone through many changes over the years, and the latest from Stanley, the FatMax Retractable Utility Knife, builds on previous improvements. A new tip design wipes crud from the blade and improves cutting accuracy by eliminating blade wobble. Easier internal blade storage access, fast blade changing mechanism, and an ergonomic, fist-fitting shape make this tool the one to reach for. Price: $11. 860-225-5111.
