Joe. Here is a photograph of my gun barrel hook scraper. This tool is now old world gunsmith tool razor sharp on three sides each side is hollow ground and glass hard very easy to break. These scrapers where only used for the finest work because files work faster. this specialized scraper was given to me by an old school gunsmith more years back than I can remember also I have never seen another this size, talking of size the battery is there for size perspective.
