Samurai Blades is one of a series of board games published in 1984 by Standard Games and by now long out of print. The game was essentially a skirmish game played on a hex board, with cardboard miniatures. Each character in the game was represented by several pieces, each depicting a different level of damage and injury. The web page at the link has lots of resources for the game, including the rules and gifs, tiffs, and jpgs of the pieces and boards. This is really useful if you have the game but have lost one of those aforementioned damage markers.
