Google "Trench Art." It's not uncommon for soldiers to pass the time by recycling things into art. Like most things, the value relies heavily on the notoriety of who made it and how well it was executed. Definitely a cool piece.
Military guys -
I found this piece of handiwork recently. It appears to mark the military service of Joe Lentini, while he was serving in Korea in '59-60. I don't know what it is beyond that, unless it was just a bit of carving and painting someone did to occupy free time? It is wood, about 14" long, semi-ovoid at the handle end, tapering to a narrow round point and carved in a spiral.
What is it? What purpose might it have served?
