This may not be a new idea but came to me the other day in my shop. I spent 8 years in the army and army national guard so I know how GI’s act. Whomever came up with the design must have known as well. To give the boys a knife with a pry to to save the blade Was very smart. They must have known that that every private with a knife will use the blade as a screwdriver and or pry bar so why not give them one on the knife. Maybe that was not the thinking but I have used that locking blade a lot over the years. I carry one with me in my shop along with a pliers in carpenter pants and both see a lot of use for weird jobs.
