looking for a heavy weight Box Cutter or Utility Folding Pocket Knife. The blade is interchangeable. Measures 6.5 inches open and 4 inches closed Original owner Push black button to release blade and insert new one. To open push silver button on side of case and pull out blade until it click and locks open. To close push silver button on side of case and gently push blade closed until it locks close Comes with a belt clip on the back of the knife. I can not locate any makers marks or words on this knife, however there is a star logo This knife would be good to have in your go bag, camping, hiking or outdoor sports bag. Even in the car to cut your seat belt off in an emergency situation. I like that the blade can be changed out with a new razor blade when it gets dull. Extra blades are not included, except for blade shown in photos
