a hand - held tool for piercing and scraping includes a handle with a short wedge - shaped blade having a pointed end for concentrating tearing forces for piercing , and a large radius tapering away from the pointed end for scraping . a thumb - rest portion is located a short distance from the handle to facilitate use of a thumb to grip and tear away packaging . the tool can also be used to scrape off sticky price labels or to clean grime , while minimizing scratching due to its plastic construction . a flexible cap can be slipped over the blade portion to protect and keep it clean . the cap can be removed and placed in the handle when using the tool , and easily removed again by pushing down on either end of the cap to raise the opposite end for grasping . the blade and handle can be injection molded as one piece from a high strength plastic .
