Steven,
Thanks for the 110 stories. I won't ask why the police took your knife at Mardi Gras.
TAH, yes there is a "+" behind the 110. That means 1991 according to your chart.
There you go, Rob. Your knife's handle material is solid ebony and the steel is 425M. Here is a good internet photo showing the difference between ebony (top) and laminated Obeechee wood.
