1 vintage World War 2 U.S./Australian knuckle fighting knife.  This WW2 knuckle knife would make an important addition to any collection. 

This Australian knuckle knife measures 10 11/16" overall.  The blade itself measures 6".  There was no sheath with this knife when we bought it.  

This WW2 knuckle knife is in excellent condition.  The blackened blade finish has surface rust.
