I read in the encyclopedia, the reason for the ebony, and sometimes Rosewood at the tip end, it was a fix for a broken cue. When a cue broke, it was sent back and this was the fix. In 1915, I think a Chicago Pool Room had 5-600 of these on the wall. In high humidity, the ebony slipped thu there hands better than Maple. That and a couple buck, and you have a cup of coffee. Jim
