This is one of the most unusual items of “Trench Art” I have found. It is a bullet, complete with shell casing and lead round. First, the bullet has been activated. Second, the lead portion of the bullet has been highly modified. The side of the copper shell casing has also been modified. A notch has been cut in and a lever has been installed in the shell casing. A small blade similar to that of a pocket knife also has been installed in the casing. When the lever is moved from the locked to the unlocked position in the shell casing, the blade pops up out of the bullet, producing a perfectly serviceable pen knife. The first time you activate the slide, it startles you. It is almost like using a switch blade!
