    Dare I say that confusion has won out over facts! My suspicion is
    that titanium has been confused with tungsten, and that tungsten has
    been confused with tungsten carbide. It's the tungsten carbide that
    is very difficult to cut, although most of it is rather brittle and
    can be broken if necessary. 

    Interesting factoid: because platinum and tungsten (not the carbide)
    have almost identical specific gravity values, tungsten has been
    used to counterfeit platinum coins. 

Happy New Year, All,
Dr. Mac
