TA knife sharpener - and a lot more. Tungsten-carbide bonded to fine, medium and rough sharpening surfaces, hardens this steel enough to dress any knife. The chisel point makes this tool useful for hacking, prying, scraping, splitting, cutting sheet metal or other rough jobs that would harm a knife. The leather-sheath handle folds out of the way for use as a sharpener, provides a convenient way to hold the tool when using it as a chisel or other tool. The leather lanyard holds the tool in sheath and secures it to belt or ring.
