Craig created this tool to help him clean the expanded metal floors. He tried a regular hoe, but it didn't work as well as he would like. He wanted a tool he could push instead of just pull. The welding teacher at the high school is his friend, so they came up with this design using part of an old hoe to connect it together. The metal is very sturdy, so it is easy to push and scrape the floor as he cleans. When it needs it, he uses a grinder to sharpen the edge.
