My friend was able to find these near his workplace where they were left by rail-workers after the spur was installed a few years ago. He gets the first Bowie knife I can make out of one of them. Hoping to get some time this coming weekend to fire up the forge I made last weekend. Four of these will hold my rail-anvil to my tree stump stack. The rest will become knives if the forge works well enough. Otherwise I'll eventually make a brake drum forge if I can find a supply of coal.
