The Rodgers One Piece Clasp knife is a minimalist knife made to British Military of Defense Specifications. The pattern dates back to the World War II Burma Knives. As rope knives go, it is about as simple as it can get.
The knife is extremely lightweight and takes up very little room. If you're looking for a spare blade for simple cutting chores this might be a perfect choice. However, the slim build might make handling more difficult if you have large hands or plan to use the knife for an extended period of time.
