Oh, how well I know the feeling.  I had a very nice point going on a piece of agate, that was in the bucket, and as I looked at it, I saw that , well hell, I can get two points out of this if I just notch it right here, and ......everything was going great, and it broke above the notch!  Well, I have one small point, and one medium point.  If I hadn't tried to get two points, I would have had a great point, about 2 1/2-3 inches long.  Oh poopee! 

  I was trying to make the finished point that I made out of the soft white stuff, just a little bit lies triangular, and it was going great, and ...... then I noticed that one of the nice and sharp ears wasn't there! 

  Oh well.  Now, I will leave well enough alone, and I will not try to get two points, in stead of one nice one.  I wil wait till I am somewhat better than I am now. 

  At least you were able to salvage a point out of it.
